Question

F(x) = -x - 4
g(x) = 2x^2 + 4x + 11
Find: (f*g)(x)

Answer 1

f(x)*g(x) =
`-2x^(3) - 12x^(2) - 27x - 44`

Explanation:

I am assuming that * means multiplication

(f*g)(x) = f(x)*g(x)

So, f(x)*g(x) = (-x-4)(
`2x^(2) + 4x + 11`) =
`-2x^(3) - 4x^(2) - 11x - 8x^(2) - 16x - 44`

=
`-2x^(3) - 12x^(2) - 27x - 44`
