Below is a graph of a quadratic function. Use the "sliders" to change the value of a, h, and k.

1. How does changing the value of [i]a[/i] impact the graph of the equation? 2. How does changing the value of [i]h[/i] impact the graph of the equation? 3. How does changing the value of [i]k[/i] impact the graph of the equation? 4. How do the values of [i]a[/i], [i]h[/i], and [i]k[/i] impact the coordinates of the vertex? 5. Based on your observations, describe how the graph of [i]y[/i] = 3([i]x[/i] - 12)^2 - 13 would compare to the graph of [i]y[/i] = [i]x[/i]^2
