Well, this is a good scenario here because from both the left and the right, as we approach x equals four, we're approaching the same value. And we know that in order for the two-sided limit to have a limit, you have to be approaching the same thing from the right and the left. And we are, and so this is going to be equal to two. Now what's the limit as x approaches two of f of x? Well, as x approaches two, we are going to be completely in this scenario right over here. Now interesting things do happen at x equals one here. Our denominator goes to zero.
