Conics: Parabolas: Introduction (page 1 of 4) Sections: Introduction, Finding information from the equation, Finding the equation from information, Word problems & Calculators. 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. In the context of conics, however, there are some additional considerations. 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.
