So in that video, we just said, hey, one could say that this limit is unbounded. But what we're going to do in this video is introduce new notation. Instead of just saying it's unbounded, we could say, hey, from both the left and the right, it looks like we're going to positive infinity. So we can introduce this notation of saying, hey, this is going to infinity, which you will sometimes see used. Some people would call this unbounded. Some people say it does not exist because it's not approaching some finite value. While some people will use this notation of the limit going to infinity.
