Graphing Quadratic Equations In this tutorial students will learn about graphing quadratic equations on a TI-84 Plus C graphing calculator.  A quadratic equation is a second degree polynomial.  The largest exponent in a quadratic equation is 2. When graphed a quadratic equation forms a parabola.  A parabola has several distinct parts named the focus, vertex, axis of symmetry and directrix.
