And for this particular function, the limit of f of x as x approaches negative infinity also looks like it is approaching two. This is not always going to be the same. You could have a situation, maybe we had, you could have another function, so let me draw a little horizontal asymptote right over here. You could imagine a function that looks like this. So let me do it like that, and maybe it does something wacky like this, and then it comes down, and it does something like this. Here, our limit as x approaches infinity is still two, but our limit as x approaches negative infinity right over here would be negative two. And of course, there's many situations where as you approach infinity or negative infinity, you aren't actually approaching some finite value.
