## Graphing Quadratic Equations with the TI-84 Plus C

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.
