The person playing teacher in this challenge says I got a B but since he's not documenting where I went wrong and telling me what the correct answers were my guess is he's just kind of making it up, so if we have a real teacher or professor in the house how did I really do on this and what were my mistakes?
1A:
lim of f(x) as x approaches 3 from the left = 5
lim of f(x) as x approaches 3 from the right = 3² - 4 = 5The two-sided limit as x approaches 3 is 5.
1B:
lim of f(x) as x approaches -4 from the left = -4
lim of f(x) as x approaches -4 from the right = 5
-4 ≠ 5, therefore it’s discontinuous at x = -4 because the two-sided limit doesn’t exist. It’s also discontinuous because there’s both a hole and a jump at x = -4.
2A:
2 - -1 = 3
lim of f(x) as x approaches -1 from the left is 3
2B:
2 - -1 = 3-13 ≠ -1, therefore the two-sided limit as x approaches -1 doesn’t exist.

Math is a category that doesn't get a lot of action here so I'm going to breathe some life into that category!Anyway, I give up so I'm offering this one to someone who knows how to do piecewise functions. I'm doing something wrong but I can't figure out where I'm going wrong but I know I'm getting something wrong because most of my answers are "limit doesn't exist".The challenge and my probably wrong answers are here:https://answermug.com/forums/topic/104095/what-does-the-bottom-question-say-on-the-classroom-words-works/view/page/3This was the challenge: less
