What do you get for \(x=1\)?

  • zzr0ck3r
Should that be \(f(x) = (\frac{1}{2})\lceil x \rceil\)?

So what this say, is take a number, find the next biggest integer and cut that in half Example f(2)=1 f(1/2) = 1/2 f(1.2) = 1

take any integer between -1 and 0, the next biggest integer is 0, cut that in half to get 0 take any number between 0 and 1, the next biggest integer is 1, cut that in half and you get 1/2 take any number between 1 and 2, the next biggest integer is 2, cut that in half to get 1. Take any number between 2 and 3, the next biggest integer is 3, cut that in half and get 1.5
