F of C would be that value. But what's the limit as X approaches C? So the limit as X approaches C, and this would be a two-sided limit of F of X, well, this is, as we approach from the left, it looks like we are approaching this value right over here. And from the right, it looks like we are approaching that same value, and so we could call that L. And L is different than F of C. And so in this case, by our formal definition, we will not be continuous at, F will not be continuous for X, or at the point X, or when X is equal to C. And you can see that there. If we tried to draw this, okay, my pencil's touching the paper, touching the paper, touching the paper. Uh-oh, if I needed to keep drawing this function, I'd have to pick up my pencil, move it over here, then pick it up again, and then jump right back down. But this rigorous definition is giving us the same conclusion.
