And what is that going to be equal to? That is going to be equal to, let's see, f of three we already figured out is three. F of one we already figured out is one. And so we get three minus one over three minus one. Well, that's gonna be two over two, which is equal to one. So there's some point between one and three where the derivative at that point, the slope of the tangent line, is equal to one. So let's see if we can solve this thing right over here.
