And actually just so we get the coordinate, what's the coordinate? The coordinate x is 0, and then y is the natural log of x is 0, this just turns out, so it's the natural log of 27. So it's the natural log of, let me figure out what that is and get the calculator out. I said I wouldn't use a graphing calculator, but I could use a regular calculator. 27, if I were to take the natural log of that, it's like 3 point, well for our purpose this is called 3.3, we're just trying to get the general shape of the graph. So 3.3, 3 point, well we could just say 2.9 and it kept going. So this is a critical point right here, the slope is 0 here.
