Some people would say it goes to negative infinity, but it's really an undefined limit. It is unbounded in the negative direction. And likewise, as we approach from the right, we get unbounded in the positive infinity direction, and technically we would say that that limit does not exist. And this would be the case when we're dealing with a vertical asymptote like we see over here. Now let's compare that to a horizontal asymptote where it turns out that the limit actually can exist. So let me delete these or just erase them for now. And so let's look at this function, which is a pretty neat function.
