If `f : R -> R` is defined by `f(x)=x-[x]- 1/2`. for `x in R`, where [x] is the greatest integer exceeding x , then `{x in R:f(x)=1/2}=`

If f:R rarr R is defined by f(x)=x-[x]-(1)/(2). for x in R, where [x]is the greatest integer exceeding x, then {x in R:f(x)=(1)/(2)}=

If f: R to R is defined by f(x)=x-[x]-(1)/(2) for all x in R , where [x] denotes the greatest integer function, then {x in R: f(x)=(1)/(2)} is equal to

If f:R rarr R is defined by f(x)=[2x]-2[x] for x in R, where [x] is the greatest integer not exceeding x,then the range of f is
