This demonstration illustrates how the graph of a quadratic function in the form
changes as the parameters a, h, and k change.
How does the graph change as a changes?
If a>1, compare the new graph to the graph when a = 1.
If 0<a<1, compare the new graph to the graph when a = 1.
How does the graph change as h changes?
If h > 0, describe the change in the graph.
If h < 0, describe the change in the graph.
How does the graph change as k changes?
