Question

If f(x) = x - 1 and g(x) = x3, what is (g•f)(8)?
Enter the correct answer

Answer 1

Answer:7^3

Explanation:

f(8)=8-1=7

g(f(8))= 7^3

Answer 2

I will assume that you meant to type (g o f)(8).

First we find f(8).

f(8) = 8 - 1 or 7.

We now find g(f(8)), which means g(7).

g(7) = 7^3 or 343

Answer:

(g o f)(8) = 343
