So now we want to evaluate f prime of negative two. Well, let's figure out what f prime of x is. So f prime of x is equal to, see, we're just gonna leverage the power rule. So three times 1 1⁄2 is 3 1⁄2 times x to the three minus one power, which is just the second power, plus the derivative of three x with respect to x. Well, that's just going to be three. And you could view that as just the power rule. If this was x to the first power, one times three x to the zeroth power.
