How many numbers are in the range of the function \(f(x) = \frac{\lceil 5x - 5\lfloor x \rfloor \rceil}5\)?
+129852 Look at the graph here :

Note the graph is "periodic" with a period of 1
It appears that in each "period," there are 6 values in the range (0, 0.2, 0.4, 0.6, 0.8 and 1 )
Thanks to Daniel for spotting that "0" should be added to the range !!!
