Find the vertices and any off-sets from the origin.
Explanation:
In algebra, dealing with parabolas usually means graphing quadratics or finding the max/min points (that is, the vertices) of parabolas for quadratic word problems.
To form a parabola according to ancient Greek definitions, you would start with a line and a point off to one side. The line is called the "directrix"; the point is called the "focus".
An excellent continuation of this procedure with illustrative graphs is here:
