Lessons 2.3 and 2.4 of Unit 2 will continue to address applications of quadratic functions, but will also incorporate the use of a graphing calculator for solving problems.

In this Lesson you saw two more ways of writing the equation of a quadratic function, each allowing you to obtain different information about the function and its graph. Analyzing quadratic functions can assist roller coaster engineers in building more enjoyable, yet safe, rides and such analysis can assist coaches in evaluating which skills must be worked on with players. Choosing the best form to model a situation facilitates this work.
