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=x
^{2}. For this lesson, we will focus on the function y=ax^{2}+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

Thanks,
Tom Adams
