Mark the correct A. 
B. [x] – x
C. not defined
D. none of these
Answer :
Given that f: R → R be such that f(x) = x – [x], where [x] denotes the greatest integer less than or equal to x
We will have same value of f for different values of x.
So, the function is not one-one.
∵ f is not bijective
∴ f does not have inverse.
