HELP PLEASE ASAP!!!

If f(x)= 3x-2 and g(x)= x^2-5, What is g(f(2))


A. 11

B. -5

C. -4

D. 3

Answer 1

Explanation:

f(x)=3x-2

f(2)=3(2)-2

f(2)=6-2

f(2)=4

When you solve f(x) for x=2, you get f(2)=4. This means that g(f(2)) is equal to g(4). Now, you can solve g(x) for x=4.

g(4)=4^2-5

g(4)=16-5

g(4)=11

g(f(2))=11

So the answer is A, 11.
