When x equals 2.01, f of x looks like it's right over here. So in this situation, we're getting closer and closer to f of x equaling one. It never does quite equal that. It actually then just has a jump discontinuity, but it seems to be approaching, this seems to be the limiting value when we approach x from values greater than, or when we approach two from values greater than two. So this right over here is equal to one. And so when we think about limits in general, the only way that a limit at two will actually exist is if both of these limits, both of these one-sided limits are actually the same thing. In this situation, they aren't.
