So let's do that. So the derivative with respect to x of u of x, of u of x, is equal to, let's see, five minus three x, the derivative of five is zero. The derivative of negative three x, well, that's just gonna be negative three. That's just negative three. If any of that looks completely unfamiliar to you, I encourage you to review the derivative properties and maybe the power rule. And now let's think about what is the derivative with respect to x, derivative with respect to x, of v of x, of v of x. Well, derivative of x squared, we just bring that exponent out front.
