Well, to do that, let's go first up here. Let's just think about what they're doing. They're asking us to take the derivative with respect to x of the product of two functions that we have some information about. 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.
