It might also help to know HOW to do it. You usually can't use Wolfram Alpha on a test. And, unfortunately, education facilities use tests a lot. It's not all bad, but not exactly representative of ability, in my opinion. Can you graph this on your own? I recommend you learn some other time, if not now!
