And it's just h bigger than x. Or actually, instead of saying h bigger, let's just, well, let me just say h bigger. So this is x plus h. That's what that point is right there. So what are going to be their corresponding y-coordinates on the curve? Well, this is the curve of y is equal to f of x. So this point right here is going to be f of our particular x right here. And maybe to show you that I'm taking a particular x, maybe I'll do a little 0 here.
