The order pair at B.....................

Answer 2

Hi there.

The answer is B choice.

Step-by-step explanation:

A function is a set of relation with no repetitive domains.

Here is an example of being a function and relation.

~ Function ~

Given the relation r = {(1,1),(2,4),(3,9),(4,16)}

As you see, there are no repetitive domains. Thus this relation is a function.

~ Relation ~

Given r = {(1,1),(1,2),(2,6),(3,28)}

As you see, there are the repetitive domains in this relation. And that is x = 1. Therefore, this relation is not a function but only a relation.
