Question #9a020

Answer 1

`p(-2) = 12`

Explanation:

I am assuming that `p(x) = x^3 + 7x^2 + 4x` and you want to find `p(-2)`.

If this is the case, then plug in `-2` for all variables `x`.

`p(x) = x^3+7x^2+4x`

`p(-2)= (-2)^3 + 7(-2)^2 + 4(-2)`

`p(-2) = -8 + 28 -8`

`p(-2) = 20 - 8`

`p(-2) = 12`
