I don't get it at all.

When you say that you "don't get it at all", what do you mean, specifically? For instance, they ask you, in part (C), for the absolute maximum value of f, which is just a matter of looking at the picture and copying down a number. Where are you stuck on this?

Please be complete, so we can figure out what lessons you're needing. Thank you!
