Using the slider, set a=1. Questions: Explain what happens as you change the values of [math]b[/math] using the slider? What remains the same, what doesn't? Why? Now let [math]a[/math] be other values besides 1. What kind of changes take place now? For most [math]a[/math]s and [math]b[/math]s, there is a long, flat tail on the left side of the graph. What is the tail called? How can we move it to be somewhere other than just the x-axis?
