If the function be such that denotes the greatest integer less than or equal to , then is:
Not defined
Explanation for the correct option:
Given function,
, i.e, only fraction part of
We need to evaluate its inverse, i.e.,
We know the greatest integer function is .
So, for different values of in , the same values of the function exists.
For example: If , then , Similarly, for , will be
Thus, will always be the same regardless the value of and hence, we cannot define .
Hence, option(C) i.e. Not defined is the correct answer.
