B. both a relation and a function
C. Neither a relation or a function
D.a function only

Answer 1

Neither a relation or a function

Answer 2

Answer: B. Both a relation and a function

Explanation:

By definition, a relation is a function if and only if each input value has one and only one output value.

For example if an input value
`x` has assigned two or more output values
`y_1` and
`y_2`, then the relation is not a function.

You can observe in the image attached that each element in the Domain has assigned one element in the Range. Therefore, you can conclude that it is a relation and a function.
