You can't see it. If I blew it up a little bit, it would look something like this. It would look something like this. It would look like that, where this is our coordinate x naught. f of x naught. And up here is our coordinate for this point, which would be the x-coordinate would be x naught plus h. And the y-coordinate would be f of x naught plus h. Just whatever this function is, we're evaluating it at this x-coordinate. That's all it is.
