A quadratic function can be written in turning point form where . Transformations of the graph of the quadratic can be explored by changing values of a, h and k.
1. Use the slider to change the values of a. Describe what happens. What type of transformation is involved here? 2. Use the slider to change the values of h. Describe what happens. What type of transformation is involved here? 3. Use the slider to change the values of k. Describe what happens. What type of transformation is involved here? 4. What are the coordinates of the turning point?
