Example: Determining a Relation, Domain, and Range from a Mapping of Names and Birthdays
Consider a mapping that assigns individuals' names to their birthdays. By following the arrows from the names to their corresponding birthdays, we can write this relation as a set of ordered pairs: . The domain comprises all the -values, which is the set of all the names: . The range contains all the -values, which is the set of all the unique birthdays: . Note that even though multiple individuals may share a birthday (such as August 2 and July 24), each distinct date is only listed once in the range.

HR Data Mapping: Workshop Range
An HR coordinator at a local company is organizing a list of employees and their birthdays on a department mapping diagram. Arrows in the diagram point from each employee's name to their birth date. To record this information mathematically, the coordinator must determine the domain, the relation as a set of ordered pairs, and the range from this diagram.
Arrange the steps the coordinator should take in the correct chronological order, starting with the first step.
