So unfortunately, I missed one class and that was when we were learning about limits. The only thing I understand is that the limit does not exist if going towards an x value, the y value's are positive and negative.

So I understand that this:

would equal 1, right? (I hope, or I really need to get help with this stuff)

But I don't understand what I'm supposed to do with this:

Would it equal 2? it says x doesn't equal two... but does. I'm confused.

Thanks to all who reply
