If this was x to the first power, one times three x to the zeroth power. Well, x to the zero is just one, so you're just left with three. And the derivative of a constant, that's just gonna be zero. So that's f prime of x. So f prime of negative two is going to be 3 1⁄2 times negative two squared is four, positive four. So plus three. So this is going to be equal to two times three plus three.
