HEEEELP :shock:
I keep getting questions like
"Find the limit of blah if X is approaching a point from the left, or right."
what does this mean?
 
I'm sorry, but we can't teach the "limits" chapter of your book. If you have a specific question, we'd be glad to help, but if you don't understand what limits are or how to find them, then I'm afraid we're out of our depth here, with respect to what we can reasonably accomplish in this environment.

If I have misunderstood your post, please accept my apologies and reply with clarification. Thank you.

sorry, what I meant was:
What do they mean by the approaching from the left or right part
 
Draw a graph. Darken a dot somewhere on the graph. Picture an ant walking along the graph. It can approach the dot from the left or from the right.

Same way with limits. If you're finding the limit of f(x) as x approaches some value "a", you can have the x-values get closer to "a" from below (that is, with x < a) or from above (that is, x > a). If the two one-sided limits agree, then "the" limit exists.
