Exploring the Quadratic Graph

F.IF.7a Graph linear, and quadratic functions and show intercepts, maxima and minima

1. How does the "h" value move the graph? (left, right, up or down) (observe how the function changes on the algebra sidebar)

2. How does the "k" value move the graph? (left, right, up or down)

3. What does (h,k) represent in the function? Maximum? minimum?
