Is this mapping diagram a function? Why or why not?

• The relation is not a function because some of the domain values are mapped to more than one range value.

• The relation is a function because each domain value is mapped to only one range value.

• The relation is not a function because some of the range values are mapped to more than one domain value.

• The relation is a function because each range value is mapped to only one domain value.
