The table shown represents a relation between x and y.

Which statement about the relation is true?

• Because each value in the range is paired with exactly one value in the domain, the relation is a function

• Because each value in the domain is paired with exactly one value in the range, the relation is a function

• Because there are some values in the range assigned to more than one value in the domain, the relation is not a function

• Because there are some values in the domain assigned to more than one value in the range, the relation is not a function
