How many numbers are in the range of the function \(f(x) = \frac{\lceil 5x - 5\lfloor x \rfloor \rceil}5\)
@CPhill, call me CHB from now on. It must hurt fingers to type it all out :D
And, additionally, I have to say that you left out the x next to the first 5 in the ceiling. I still don't know if it is infinity or just 6..
