you should be familiar with the vertex form of a parabola ...
sub in the given vertex coordinates and the coordinates of the given point ... solve for , then graph.
btw ... next time state what you are graphing. if you had not mentioned a vertex, I would've had no idea what you wanted graphed in the first place.
