Well, here our x is now 3 plus delta x. It's the same thing as this one right here. It's x naught plus h. I could have called this 3 plus h just as easily. So it's 3 plus delta x up there. So what's the y value going to be? Well, whatever x value is, it's on the curve, it's going to be that squared. So it's going to be, this is going to be the point 3 plus delta x squared.
