Move the sliders to change the values of a, b, & c and observe what happens to the graph.
Let a = 0. What can you see? Vary b - what is changing and what is staying the same? Vary c - what is changing and what is staying the same? Let a = 1. What can you see now? Vary b - what is changing and what is staying the same? Vary c - what is changing and what is staying the same? Now vary the value of a. What happens when a is a large positive number? What happens when a is a small positive number? What happens when a becomes negative?
