neither one-one nor onto
one-one and not onto
one-one and onto
not one-one but onto
neither one-one nor onto
Hint:
In this question, we have to find the type of function if is defined by . A function 
is said to be one-one if different elements of A have different images in B, and a function is said to be onto if for all 
, there exists 
such that f (x) = y.
The correct answer is: not one-one but onto
