The range of function is values on the y-axis: R=[-7,2].
What is function?A function is a mathematical concept that describes the relationship between two sets of numbers. It is a rule that assigns to each input (or element in the domain) exactly one output (or element in the range). In simpler terms, a function is like a machine that takes in a number and produces another number as output, according to some specific rules. The input is usually denoted by x, and the output by f(x), which is read as "f of x". Functions can take many forms, such as linear, quadratic, trigonometric, exponential, logarithmic, and more. They are widely used in mathematics, science, engineering, and many other fields to model and analyze various phenomena.
Here,
To find the range of a function, you need to determine all possible output values of the function. Start by identifying the function's domain, which is the set of all possible input values of the function. Once you know the domain, apply the function to each input value in the domain and record the corresponding output values. Once you have a list of output values, identify the smallest and largest values in the list. These values represent the range of the function. For example, consider the function f(x) = 2x + 1. The domain of this function is all real numbers.
To find the range, apply the function to several input values in the domain:
f(-3) = -5
f(-2) = -3
f(-1) = -1
f(0) = 1
f(1) = 3
f(2) = 5
f(3) = 7
These output values give us a set of possible output values, which are {-5, -3, -1, 1, 3, 5, 7}. The smallest value in the set is -5 and the largest value is 7, so the range of the function is [-5, 7].
Note that for some functions, it may be difficult or impossible to find the exact range. In such cases, you can use techniques such as graphing or calculus to estimate the range.

Your sister has R375 000 and wants to retire. She expects to live for another 25 years, and she also expects to earn 8% on her invested funds. How much could she withdraw at the beginning of each of the next 25 years, and end up with zero in the account?
Answer:
Step-by-step explanation:
Your sister can use the formula for calculating the present value of an annuity to determine how much she can withdraw each year.
The formula for the present value of an annuity is:
PV = Payment x (1 - (1 + r)^-n) / r
Where:
- PV is the present value of the annuity
- Payment is the amount of each withdrawal
- r is the annual interest rate
- n is the number of periods (in this case, 25 years)
We can rearrange this formula to solve for Payment:
Payment = PV x r / (1 - (1 + r)^-n)
We know that your sister has R375 000 to start with, and she wants to end up with zero in 25 years. So, her present value (PV) is R375 000, and we can assume her future value (FV) is zero.
Using the future value formula, we can calculate the interest rate she needs to earn in order to end up with zero in 25 years:
FV = PV x (1 + r)^n
0 = 375000 x (1 + r)^25
(1 + r)^25 = 1
1 + r = (1)^1/25
r = 0
This means that your sister needs to withdraw all of her money over the 25 years in order to end up with zero at the end.
Her withdrawal each year would be:
Payment = PV x r / (1 - (1 + r)^-n)
Payment = 375000 x 0.08 / (1 - (1 + 0.08)^-25)
Payment = R34,028.82 per year
Your sister can withdraw R34,028.82 at the beginning of each year for the next 25 years, and she will end up with zero at the end, assuming she earns an 8% return on her invested funds.

Determine a function type that
could represent the values in the
table.
x f(x)
0 −18
1 −15
2 −12
3 −9
4 −6
◻ linear
◻ quadratic
◻ exponential
Answer: Linear
Step-by-step explanation:
Since the difference between consecutive values of f(x) is constant, this suggests that the function could be linear. To confirm this, we can calculate the differences between consecutive values:f(1) - f(0) = -15 - (-18) = 3
f(2) - f(1) = -12 - (-15) = 3
f(3) - f(2) = -9 - (-12) = 3
f(4) - f(3) = -6 - (-9) = 3
Since the differences are constant and equal to 3, this confirms that the function is linear.
To find the equation of the linear function, we can use the slope-intercept form of a linear equation:
y = mx + bwhere m is the slope and b is the y-intercept.
We can use the first two points (0, -18) and (1, -15) to find the slope:
m = (change in y) / (change in x) = (-15 - (-18)) / (1 - 0) = 3
Now we can use the slope and one of the points to find the y-intercept:
y = mx + b
-18 = 3(0) + b
b = -18
Therefore, the equation of the linear function is:
f(x) = 3x - 18
So the function type that could represent the values in the table is linear.

The average rate of change representing the state whose temperature is decreasing slower is given as follows:
-1.5ºF/day.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For Maine, in 9 days, the temperature fell by 13.5ºF, hence the rate is given as follows:
-13.5/9 = -1.5ºF/day.
For Connecticut, in 2.5 days, the temperature fell by 6.25ºF, hence the rate is given as follows:
-6.25/2.5 = -2.25 ºF/day.
A slower decline is in Maine, as it has a lower rate of change.

What is binοmial distributiοn?Binοmial distributiοn is a prοbability distributiοn that describes the number οf successes in a fixed number οf independent trials, where each trial can οnly have twο οutcοmes: success οr failure.
Accοrding tο questiοn:
Let X be the number οf machines that need cοrrecting adjustments during a day's prοductiοn run, and let p = 0.2 be the prοbability that any οne machine needs cοrrecting.
Then, X fοllοws a binοmial distributiοn with parameters n = 6 (the number οf machines) and p = 0.2 (the prοbability οf a machine needing cοrrecting).
The prοbability οf X is:
P(X > 2) = 1 - P(X <= 2)
Tο calculate P(X <= 2), we can sum the prοbabilities οf X taking οn the values 0, 1, and 2:
P(X <= 2) = P(X = 0) + P(X = 1) + P(X = 2)
P(X = 0) = (6 chοοse 0) * 0.2⁰ * 0.8⁶ = 0.2621
P(X = 1) = (6 chοοse 1) * 0.2¹ * 0.8⁵ = 0.3932
P(X = 2) = (6 chοοse 2) * 0.2²* 0.8⁴ = 0.2621
Therefοre,
P(X <= 2)
= 0.9174
And
P(X > 2)
= 1 - P(X <= 2)
= 1 - 0.9174
= 0.0826

A square wrestling mat has a perimeter of (12x−32)
feet. Write an expression in simplest form that represents the side length (in feet) of the mat.
Answer:
The perimeter of a square is given by the formula P = 4s, where s is the side length. In this case, we are given that the perimeter is (12x - 32) feet, so we can set up an equation:
P = 4s
(12x - 32) = 4s
To solve for s, we can divide both sides by 4:
(12x - 32)/4 = s
Simplifying the expression on the left:
3x - 8 = s
Therefore, the expression in simplest form that represents the side length of the square wrestling mat is 3x - 8 feet.

Evaluate the following limit. Enter the exact answer in fraction form, if necessary.
Answer:
To evaluate this limit, we can factor out the highest power of x from the numerator and denominator, which is x^14. Then, we can divide both the numerator and denominator by x^14. This gives:
lim x→∞ (6x^14 + 8x^11 + 37x^14) / x^14
= lim x→∞ (6x^14 / x^14 + 8x^11 / x^14 + 37x^14 / x^14)
= lim x→∞ (6 + 8 / x^3 + 37)
= 6 + 0 + 37 (since as x approaches infinity, 8/x^3 approaches zero)
= 43
Therefore, the value of the limit is 43.

why does this series [tex]tan(2^{-n} )[/tex] converge?
*its a series from 2 to infinity, but there is no symbol for that.
The series [tex]\tan(2^{-n})[/tex] is convergent.
What is convergence of series?In mathematics, the cοnvergence οf a series refers tο the behaviοr οf the series' partial sums as mοre terms are added. A series cοnverges if its sequence οf partial sums apprοaches a finite limit, which is called the sum οf the series. If the sequence οf partial sums dοes nοt apprοach a finite limit, the series diverges.
The series [tex]\tan(2^{-n})[/tex] converges because of the following reasons:
As n increases, [tex]2^{-n}[/tex] becomes very small, which makes [tex]\tan(2^{-n})[/tex] close to its linear approximation. Therefore, we can use the linear approximation of [tex]\tan(2^{-n})[/tex] to estimate its value.
The linear approximation of [tex]\tan(2^{-n})[/tex] is [tex]2^{-n}[/tex], which means that [tex]\tan(2^{-n})[/tex] ≈ [tex]2^{-n}[/tex] when [tex]2^{-n}[/tex] is small.
Since the series [tex]2^{-n}[/tex] is convergent, by comparison test, the series [tex]\tan(2^{-n})[/tex] is also convergent.
Alternatively, we can also use the fact that the series tan(x) is convergent for x ∈ (0, π/2), and since [tex]2^{-n}[/tex] → 0 as n → ∞, we have [tex]\tan(2^{-n})[/tex] → tan(0) = 0, which implies that the series [tex]\tan(2^{-n})[/tex] is convergent.

The amount and the compound interest on a sum of Rs. 62500 are Rs. 65625 and Rs. 3125, respectively.
Calculating the amount and the compound interestGiven:
Principal amount (P) = Rs. 62500
Rate of interest (R) = 5%
Time period (t) = 1 year
Interest is compounded yearly.
Formula for calculating compound interest is given as:
A = P(1 + R/100)ᵗ
where A is the amount.
Using this formula, we can find the amount (A) after one year:
A = 62500(1 + 5/100)¹
A = 65625
Therefore, the amount after one year is Rs. 65625.
To find the compound interest, we can subtract the principal from the amount:
Compound Interest = A - P
= 65625 - 62500
= 3125
