In the following applet one can examine the effects of changing the values of a, h, and k in the graph of the function y = a | x + h | + k.

  1. Find values for a, h, and k so that the graph of y = a | x + h | + k. passes through the two green points.

  2. Are there other values of a, h, and k that will work?
