Provide an appropriate response.Compare the graphs of 
and 
. What restrictions, if any, must be placed on a, h, and k if both graphs are to have the same x-intercepts?
What will be an ideal response?
The graphs are reflections of each other across the line y = k. If the graphs are to have the same x-intercepts, k must be 0. (No restrictions on a or h are necessary.)
