Quadratic Graphs

Move the sliders to see how changing the parameters a, b, and c affects the shape and position of the graph.
1. If a is negative, what happens to the graph?
2. As |a| increases, what happens to the graph?
3. How does changing c affect the graph?
4. b affects position of the vertex. Change b while keeping a and c the same. Try to find the rule for the x-coordinate of the vertex based on the values of a, b and c.
