So the only choice where all of that is true is this first one. Whether we approach two from the right-hand side or the left-hand side, we are approaching positive infinity. Now the other way you could have deduced that is say, okay, as we approach two, the numerator is going to be positive, because two is positive. 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.
