Description: 
Guided activities with the Graph Explorer applet, designed to let students learning about quadratic functions explore: the parabolic shape of the graphs of quadratic functions; how coefficients affect the position and scale of the graph; how the graph of the function relates to those of its factors; the location of the axis of symmetry; and "completing the square."

Comment:  A nice, clean webpage with a good perspective on quadratic equations (as the product of linearlyrelated quantities). Great lab exercises as well, I actually learned something about quadratics.

Comment:  An excellent tool. Takes a bit of upfront knowledge to get started. Limited use with function notation.
