What's the limit as x approaches one from the left? And of course, these are of h of x. Gotta write that down. So of h of x, right over here. Well, as we approach from the left, we are going to, looks like we're going to positive infinity and it looks like the limit of h of x as we approach one from the right is also going to positive infinity. And so since we're approaching, you could say the same direction of infinity, you could say this for B. So B meets the constraints, but let's just check C to make sure. Well, you can see very clearly, x equals one, that as we approach it from the left, we go to negative infinity and as we approach from the right, we go to positive infinity so this, once again, would not be approaching the same infinity, so you would rule this one out as well.
