If the function `f: R->R` be such that `f(x) = x-[x],` where `[x]` denotes the greatest integer less than or equal to `x,` then `f^-1(x)` is

Text Solution

Verified by Experts

Given,
`f(x)=x−[x] `
` [x]` is a greatest integer function.
Hence, we will have same values of the function for the different values of x.
As we considering integer only not fraction part.
` f^(−1)` can not be defined
