Well, if we're taking the derivative of the product of two functions, you could imagine that the product rule could prove useful here. So I'm just gonna restate the product rule. This is going to be equal to the derivative of the first function, f prime of x, times the second function, not taking its derivative, plus the first function, not taking its derivative, f of x, times the derivative of the second function, h prime of x. So if you're trying to find g prime of three, well, that's just going to be f prime of three times h of three plus f of three times h prime of three. And lucky for us, they give us what all of these things evaluate to. f prime of three, right over here, they tell us. f prime, when x is equal to three, is equal to six.
