Ordered+Pairs

The following sets of ordered pairs represent functions because they have one or more of the following characteristics:
 * Each x-value only appears once
 * If an x-value appears more than once, then each x-value has to be paired with the same y-value

The following set of ordered pairs does **NOT** represent a function because they have the following characteristic:
 * If an x-value appears more than once and is paired with different y-values
