Example: Finding the Domain and Range of the Relation {(1,1), (2,8), (3,27), (4,64), (5,125)}

Example: Finding the Domain and Range of the Relation {(1,3), (2,6), (3,9), (4,12), (5,15)}

A warehouse manager records the aisle number and the total number of pallets stored in that aisle as a set of ordered pairs: {(12, 45), (15, 30), (18, 55)}. Which of the following sets represents the domain of this relation?

An IT technician logs the number of help desk tickets resolved and the hours spent working on them as a set of ordered pairs: {(12, 4), (18, 6), (9, 3)}. The domain of this relation is the set {4, 6, 3}.

A retail manager tracks the number of hours a part-time employee works ($x$) and their total weekly earnings in dollars ($y$). The data for three weeks is recorded as the following set of ordered pairs: {(12, 180), (15, 225), (20, 300)}. Match each mathematical term with the correct set representing that part of the relation.
