This sketch is a simple look at the vertex form of a quadratic function. The sliders control the paramenters.
1) Play with the controls, and describe what a, h and k control about the function.
2) See it you can predict the vertex, the y-intercept or the x-intercepts for your function.
3) Try entering a standard form in the input bar and see if you can match the vertex form.
