Question
The function 
- one-one
- onto
- Both one-one and onto
- neither one-one nor onto
Hint:
In this question, we have to find the type of function if 
A function 
is said to be one-one if different elements of A have different images in B, a function is said to be onto if for all 
, there exists 
such that f (x) = y.
The correct answer is: neither one-one nor onto
We have f(x)=x-[x].
Clearly, f(x)=0 for all x 
Z.
So, f(x) is not one-one function.
Also, range= [0,1) 
R
So, f(x) is not into function.
