Both vertical and horizontal asymptotes. So it looks something like this. So this right over here is 1 over x for x is greater than 0. So this is 1 over x when x is greater than 0. So all it's saying here, and you can see it pretty clearly, is the slope right over here, the slope of the tangent line is 1. And so you see, when you look at the derivative, the slope right over here, the derivative should be equal to 1 here. When you get close to 0, you have a very, very steep positive slope here.
