Answer: -7

Step-by-step explanation:

Plug in 3 for x^2-2, you would then get 7 since 3^2 is 9 and you subtract it to get the answer for g(x).  Plug in that number for f(x) and you would get -7 as a result. -2(7) would equal to -14 since you are multiplying a positive and negative and adding it will still be -7 which makes your initial answer wrong.
