So let's make a little table here. Make a little table, a little bit neater. So x, x, h prime of x right over here. We know at x equals two, h prime of two is zero, that's our critical point. But let's try, I don't know, let's see what happens when x is equal to one, and then let's see what happens when x equals three. We're just sampling points on either side of two. And let's see, we are going to have, when x is equal to one, h prime of one is three times one minus two squared.
