Answer 5

I would just plug in numbers and see which one matches

Lets say x=1

Answer 6

Okay

Answer 7

Plug that into g(x)
You get
-1+3=2

Answer 8

Now plug 2 into f(x) what do you get?

Answer 9

Oh, 16

Answer 10

Yea. Because you're replacing what you got for g(x) for x in f(x)

Answer 11

Now plug 1 into each of your answer choice and see which one gives you 16

Answer 12

So, C
