Question

If given f(x) = –4x – 2 and g(x) = 2x, what is (f · g)(x)?

A.
(f · g)(x) = –6x – 4
B.
(f · g)(x) = –8x2 – 4x
C.
(f · g)(x) = –6x – 2
D.
(f · g)(x) = –16x2 – 4x

Answer 1

It's actually multiplying two functions together
(-4x -2)(2x)
= -8x^2 -4x
so the answer should be B

Answer 2

I hope so
