1. ## Professor says no calculator, got to memorize certain graphs?

Professor says no calculator, only for homework. But I'm wondering, for graphs like y = lnx when finding limits would it be safe to say that I am expected to know what the graph looks like?

yes.

3. Is there a lot of the to memorize? Or just the basic ones like sinx, cox, etc. logx, lnx? And I guess just practicing more and more limit problems.

This question is impossible to answer. I may as well ask you how long is a piece of string.

Surely your class notes contain all the material you're expected to know and your instructor flagged the material to be memorised.

I agree with Mr. F here, friend. I will say, however, that the graphs of polynomials and the early transcendentals ( basic trig, logarithimic, etc...) are a biggie.

I wouldn't sweat it. When then time comes to know the graph, you will know the graph.
