And we call that value, that value that f of x seems to be approaching as x approaches c, we call that value L, or the limit. And so the way we would denote it, is we would call that the limit. We don't have to call it L all the time, but it's referred to as the limit. And the way that we would kind of write that mathematically, is we would say the limit of f of x as x approaches c is equal to L. And this is a fine conceptual understanding of limits. And it really will take you pretty far. And you're ready to progress and start thinking about taking a lot of limits. But this isn't a very mathematically rigorous definition of limits.
