Question

F(x) = -x-1g(x) = –6x^2– x+1Find: f (x) · g(x)

Answer 1

Given data:

The first function is f(x)=-x-1.

The second function is g(x)=-6x^2-x+1.

The expression for f(x).g(x) is,

`\begin{gathered} f(x)\text{.g(x)}=(-x-1)(-6x^2-x+1) \\ =6x^3+x^2-x+6x^2+x-1 \\ =6x^3+7x^2-1 \end{gathered}`

Thus, the product of given functions is 6x^3+7x^2-1.
