Looking Back…. In our previous lesson, we solved quadratic function by . Regression. By, Tyler . Laufersweiler. Quadratic Regression. Title: Finding . the equation of curves throughout . life . using quadratic regression. This lesson uses a graphing calculator and Geometer’s Sketchpad to find the function of curves throughout the world. This hands-on lesson allows students to explore quadratic regression using their calculators (quadratic regression applet). Students will use Geometer’s Sketchpad to record data points and their calculators or a website to generate a quadratic function using the data that represents the curve. .
