Okay. I have done all these problems and I would like it if some one put all the answers up so i can see if i'm right
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
