Question

If F(x) = x + 6 and G(x) = x4, what is G(F(x))?

Answer 1

D. (x+6)^ 4

We are given f(x)=x+6, so all we do is put the f(x) value in g(x), Hence our answer is
`(x+6)^(4)`

Answer 2

g(f(x)) = (x + 6)^4.

Explanation:

We replace the in x^4 ( ie g(x)) by (x + 6) ( ie f(x)):

g(f(x)) = (x + 6)^4
