And then over here, as you approach two, cosine of anything can never be greater than one. It's going to approach one, but be less than one. So if this is less than one, as x approaches two, it becomes one when x is equal to two. Well then this right over here, one minus something less than one is going to be positive. So you have a positive divided by a positive, so you're definitely going to get positive values as you approach two. And we know, and they've already told us that these are going to be unbounded based on the choices, so you would also pick that. But you should also feel good about it, that the closer that we get to two, the closer that this value right over here gets to zero, and the closer that this value gets to zero, the closer we get to one, the closer we get to one, the smaller the denominator gets, and then you divide by smaller and smaller denominators, you're going to become unbounded towards infinity, which is exactly what we see in that first choice.
