And let's think about another scenario. Let's think about a scenario, and actually, maybe let's think about a scenario where the limit, the two-sided limit doesn't even exist. So, there are my axes, X and Y, and let's say it's doing something like this. Let's say it's doing something like this, and then it does something like this and goes like that. And let's say that this right over here is our C. And so, let's see, this is F of C right over here. That is, let me draw it a little bit neater. That is F of C, and it does look like the limit as X approaches C from the left.
