Thanks TheMathProf. Kudos for another awesome post.

@Noober: Your justification for b is a little itchy. They want you to prove that the function is concave up for all x between 1 and 3. Basically just state this fact (2xln(x) + x > 0 for all x between 1 and 3) and I think you will get credit (correct me if I am wrong).
