Copy of Quiz: Adding Functions Graphically
In the applet below, the graphs of functions f and g are shown.  
Your task is to move the LARGE BLACK OPEN POINTS (initially seen up top) and use them to plot 2 points that lie on the graph of the sum of these two functions, f + g.  (Use the points on the two functions to help you do this).  Once you do, select the Check Points checkbox to check your work. 
Be sure to zoom in/out if you need to.
