So we've got this function f of x that is piecewise continuous, it's defined over several intervals here. For x being, or for zero less than x, being less than or equal to two, f of x is natural log of x. For any x is larger than two, well then f of x is going to be x squared times the natural log of x. And what we want to do is, we want to find the limit of f of x as x approaches two. And what's interesting about the value two is that that's essentially the boundary between these two intervals. If we wanted to evaluate it at two, we would fall into this first interval, f of two. Well, two is less than or equal to two, and it's greater than zero.
