Answer: g(f(4))=9
Step-by-step 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.
