Answer:
(f o g) (x) = 36x² + 3
(g o f) (x) = 6x² + 18
Step-by-step explanation:
f(x) is x² + 3
g(x) is 6x
(f o g) (x) means for all xs in f replace it with g(x) or 6x
(f o g) (x) = (6x)² + 3 - see 6x is in place of x and 6x is g(x)
(f o g) (x) = 36x² + 3
(g o f) (x) = 6(x² + 3)
(g o f) (x) = 6x² + 18

Answer:</h3>
1. Yes, the x-intercept is 3 1/2
2. Yes, the y-intercept is -7
3. No, the slope is 2
<h3>
Explanation:</h3>
6x -3y = 21
-3y = -6x + 21
y = 2x - 7
Answer:
77.2
Step-by-step explanation:
In general, an average rate of change of a function is a process that calculates the amount of change in one item divided by the corresponding amount of change in another. Using function notation, we can define the average rate of change of a function f from a to b as
![A=\dfrac{f(b)-f(a)}{b-a}.](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D.)
1. The average rate of change in the number of living wage jobs from 1997 to 1999 is
![A=\dfrac{745-635}{1999-1997}=\dfrac{110}{2}=55.](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B745-635%7D%7B1999-1997%7D%3D%5Cdfrac%7B110%7D%7B2%7D%3D55.)
2. The average rate of change in the number of living wage jobs from 1999 to 2001 is
![A=\dfrac{800-745}{2001-1999}=\dfrac{55}{2}=27.5.](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B800-745%7D%7B2001-1999%7D%3D%5Cdfrac%7B55%7D%7B2%7D%3D27.5.)
