So this whole thing has to be approaching a positive value, or it could become unbounded in the positive direction. As we'll see, this is unbounded, because this thing is even closer to one than this thing. And you would see that if you have a calculator. But needless to say, this is going to be unbounded in the positive direction, so we're going to be going towards positive infinity. So these two choices have that. And we can make the exact same argument as we go, as we approach x in the negative, or from below, as we approach two from below, I should say. So that's x, and that is f of x.
