Answer:

B

Step-by-step explanation:

You are making composite functions, since all the answers provided dont fit, I only suggest to clearify that the lone term in the B option, is actually 45x and not 45.

If this is the case, composite functions means that you eval the expresion g(x) in every x variable found in f(x).

Using this, it gives you that f(g(x))= -40x^{2} +25x+45
