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.[br]1. What happens when the value of r is changed?[br]2. What is the difference between values of a that are less than one and greater than one?[br]3. What happens to the transformation equation when h is negative?[br]4. Which values define the vertex or end-point of the function? [br]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.
