And the way we see it, we see that our f of x seems to be, as x gets closer and closer to c, it looks like our f of x is getting closer and closer to some value. It's getting closer and closer to some value right over there. I'll even draw it, maybe I'll draw it with a more solid line. And that was actually only the case when x was getting closer to c from the left, from values of x less than c. But what happens as we get closer and closer to c from values of x that are larger than c? Well, when x is over here, f of x is right over here. And so that's what f of x is, is right over there. When x gets a little bit closer to c, our f of x is right over there.
