It is the end of Christmas vacation and I can't remember how to do this one problem for my calculus class and it is really bothering me. I uploaded it to imageshack because I can't type it in here.

I know that it is a relatively easy problem but I keep getting the wrong answer. It is multiple choice but I still need to show work. Thanks to anyone who can answer this!
