Assume that f(3) = 4.  Name a point that must be on the graph of y = 2*f(2x) + 1/2.

the   2x    will   'shorten'  the function so that   instead of 3   the value will be  4   at     1 1/2

   then  the 2 *    will increase the  value to   8       then add the   1/2   = 8 1/2

 

1 1/2  ,  8 1/2     should be on the graph
