Question

# If

- one-one onto function
- an onto function only
- an identity function
- an into function only

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, and a function is said to be an identity function if the function is both one-one and onto.

## The correct answer is: an identity function
