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.
