Question

Given f(x) = x - 7 and g(x) = x2 Find g(f(4))​

Answer 1

Answer: g(f(4))=9

Explanation:

To find g(f(4)), you first need to solve f(4). After you find that value, you plug that value into g(x).

f(4)=4-7 [subtract]

f(4)=-3

Now that we know h(4)=-3, we plug -3 into g(x).

g(-3)=(-3)² [exponent]

g(-3)=9

After we have plugged in f(4) into g(x), we got g(f(4))=9.
