Select one or more functions with the check boxes and use the sliders to change the values of r, a, h and k. The transformation equations will show how the equations changes as the values change. Answer the following for each of the three functions.
1. What happens when the value of r is changed?
2. What is the difference between values of a that are less than one and greater than one?
3. What happens to the transformation equation when h is negative?
4. Which values define the vertex or end-point of the function?
5. Find the equation when the vertex/end-point is at (4, 12), it is reflected across the x axis and compressed by a factor of 1/2.
