So let's say we have that point right there. Actually, let me do it even further out, just because it's going to get messy otherwise. So let's say we have this point right here. 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?
