I was at the MAC today and came up with a few questions. First of all, when doing the squeeze thrm, if we get a value for the left (say F(x)) that is equal to the value on the right (say g(x)) then the middle value (say h(x)) should be equal to those values. But what happens if we get a value for the left and right that don't match? I mean, I know that instantly the middle limit is undefined, but are we doing something else to figure out what that undefined answer is?

Secondly, I was going over limits with one of the MAC people, and he was talking about graphs. He kept saying we need a graph in order to complete certain limits, and I don't remember ever using a graph to compute limits. Because of this we both ended up confused haha. What are your thoughts on this?

Thridly, will there be limit problems on the test like in section 2.3? And will each problem be solved by either conjugate multiplication, factoring, simplifying, absolute value, or common denominator?

Thanks
