Find g[h(x)] and h[g(x)]

1.g(x)=x+4

h(x)=x+9

2. g(x)=|x|

h(x)= x - 3

3.g(x)=x^2-4

h(x)=x+1

if f(x) =x^2, g(x)=3x, and h(x) = x-1 find each of the following

4. g[f(x)]

5.[f o h](3)

6.[f o h](-2)

Find the inverse of each function

7. I already know I got 7 right

8. g(x)= (-3x+1)/2

9. h(x) = 4x^2 +12x + 9

Are the following functions inverses

10. f(x) = (2x-8)/2

11. g(x) = x +4

(Cool)
