Here is a geogebra java app that I created for a lesson.
The goal of this lesson is to become familiar with the graphs of quadratic equations. Remember a quadratic equation has the parent function of y=x2. For this lesson, we will focus on the function y=ax2+bx+c. We will explore how a, b, and c transform the parent function and recognize the relationship between x and y in a table of values. Go to
Tom, Thanks so much for this lesson! I have added it to my website.
Thanks again for a great lesson!
