Answers
Answer:
1) (f+g ) x = (x²-4)+ (x+2) = x²+ x –2
2) (f - g ) x = (x²-4) – (x+2) = (x²-4)+ ( -x - 2) = x²–x–6
3) (f × g ) x = (x²-4)(x+2) = x³+2x²– 4x – 8
4) (f / g) x = (x²-4) / (x+2) = x – 2
5) ( f + g ) 4 = (x²-4)+ (x+2) = ((4²)-4)+ (4+2) = ( 16–4) + (6) = 12+6 = 18
I hope I helped you^_^

Given the exponential function f(x) and the logarithmic function g(x), which of the following statements is true?
*Exponential function f of x equals 3 to the power of x minus 1 that increases to the right passing through the point 0 comma 0 and logarithmic function g of x equals log in base 3 of x minus 3 increasing from left to right passing through the point 1 comma negative 3
A. As x approaches infinity, f(x) approaches infinity, and g(x) approaches 0.
B. As x approaches infinity, f(x) approaches 2, and g(x) approaches 0.
C. As x approaches infinity, f(x) approaches 2, and g(x) approaches infinity.
D. As x approaches infinity, f(x) approaches infinity, and g(x) approaches infinity.
Answers
Answer:
As x→∞, f (x)→∞ and g(x)→∞.
Step-by-step explanation:
Looking at the graph there is no asymptote interrupting either f(x) or g(x) so when the graphs will continue on they will just approach infinity. Also just took this assessment and got a 100%.

An apartment building contains 250 apartments. There are 50 more 2-bedroom apartments than 1-bedroom apartments. How many apartments of each type are there
Answers
Answer:
100
Step-by-step explanation:
Answer:
100 1- bedroom and 150 2- bedroom
Step-by-step explanation:
let x be the number of 1- bedroom apartments , then
x + 50 is the number of 2- bedroom apartments , so
x + x + 50 = 250 ( subtract 50 from both sides )
2x = 200 ( divide both sides by 2 )
x = 100
There are 100 1- bedroom apartments and 100 + 50 = 150 2- bedroom
Let f(x)=x^3+3 and g(x) = 2x^2 + 2x +1. What is g(f(-2))?
Answers
Answer:
41
Step-by-step explanation:
This composite function can be easily solved
First solve f(-2)
f(-2)=(-2)³+3
f(-2)=-8+3=-5
Now plug -5 for x in function g(x)
=2(-5)²+2(-5)+1
=50-10+1
=41

Answer:
41
Step-by-step explanation:
g(f(-2)) = g((-2)³ +3) = g(-8+3) = g(-5)
= 2(-5)² +2(-5) +1 = 50 -10 +1
g(f(-2)) = 41

Let's solve for x using trigonometric relation ( Cos )
we know,

7/9+6/8+6/3=
I really need the answer
Answers
Answer:
[tex]\frac{1}{30}[/tex]
Step-by-step explanation:
Take it in steps. First, find 7/9+6. Then we'll find 8+6/3, and, finally, we'll divide the two answers.
1:
7/9+6 = 7/15
2:
8+6/3 = 14/3
3:
[tex]\frac{\frac{7}{15}}{\frac{14}{3}}[/tex] or [tex]\frac{7/15}{14/3}[/tex]
Then take that in chunks: 7/14 and 15/3.
7/14 = 1/2
15/3 = 5/1
Use those to rewrite it as [tex]\frac{1/5}{2/3}[/tex].
1/5 = .2
2/3 ≈ .6667 so we'll keep writing it as 2/3
[tex]\frac{\frac{.2}{2}}{3}[/tex]
.2/2 = .1, so:
[tex]\frac{.1}{3}[/tex] = [tex]\frac{1}{30}[/tex]

) A real estate agent sells a unit for $800 000. The commission rate is 2.75% of the selling price. Calculate the commission. (A) $25 000 (B) $27 750 (C) $220 000 (D) $22 000
Answers
Answer:
The answer is (D) $22 000
Step-by-step explanation:
800,000/100 = 8,000
I did this to show 1% of 800,000 is 8,000 (To find 1% of a number always divide it by 100)8,000*2.75=22,000
I did this because since I know 8,000 is 1% percent of the price I can times it by the percentage rate to find how much the commission is. Also note that there are other ways to solve this equation that may suit you better, this is the way I do it and I find it much more faster.For the following system of equations, determine how many solutions there are. y = 5(x − 4) and 4x + 12 = −y
