Hi Mrs. Carlson,
I think that one of the answers on set #1 is wrong. #30's answer says E but I don't think that is correct because the question says that the limit as x approaches 1+ is -inf. and choice E is not correct. I think the answer should be C. I would appreciate it if you could check it out.
Thank you.

Same here. I got that it should be C too.
I thought it was C too because it says the second derivative is greater than 0 when x < 1, meaning it is concaved up. Also, the second derivative is less than zero for x > 1, meaning it is concaved down. However, answer E is concaved up when x >1.
