Answer 2

Function

Explanation:

Given is the relation with ordered pairs

`{(0, 1), (3, 5), (2, 2), (–1, 4)}`

To check whether this relation is a function.

We find that in the given relation is domain is

`{0,3,2,-1}` and range is

{1,5,2,4}

We find that each element in the domain has a unique image in range.

Hence by definition of a function, this relation is a function.
