Question

# If is defined by

- 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
