 [To see this, note first that  must be constant in intervals where  is constant, and only graph (b) has this property. Also  for , so the graph of  should look like the graph of f stretched vertically in regions where  is between -1 and .75, but for  above .75 (and below 3.25) applying g to the result always gives just 1.5  just like graph (a).]
