Ok, havin' a bit of a problem with a parabola, well, problem...

First off, I can't graph y=x squared.

Or any parabola for that matter.. I can find the vert and the axis of symmetry,however, i'm havig trouble graphing points (again, I can't graph y=x squared), and it seems to me like it's just educated-guess work on that portion, randomly plotting points based on the aos and whether or not it's wider or narrower than y=x sqrd....

Help.. Please.
