During a logistics training session, you are reviewing a routing log that maps delivery driver IDs ($x$) to their assigned loading zones ($y$). The log is represented by the following set of ordered pairs: {(101, 4), (102, 5), (103, 4), (104, 6)}. Recalling the criteria for functions, which of the following statements correctly classifies this set?

In a corporate directory, a log tracks the assignment of Employee IDs ($x$) to Workspace IDs ($y$). If the current assignments are represented by the set {(101, 22), (102, 25), (103, 22)}, the relationship is a function, but it is NOT a(n) ____ function because the Workspace ID 22 is assigned to two different employees.

A logistics coordinator is auditing a database that maps Driver IDs ($x$) to Vehicle Numbers ($y$). The audit reveals the following set of ordered pairs: {(101, 20), (102, 21), (103, 20)}. This mapping represents a one-to-one function.

An operations coordinator is auditing three different data logs to ensure they are recorded correctly. Match each set of ordered pairs (x, y)—representing Driver IDs and their assignments—with the correct mathematical classification of its relationship.

As an HR systems analyst, you are auditing a digital log that pairs Employee IDs ($x$) with their assigned Secure Lockers ($y$) as a set of ordered pairs. Recalling the standard mathematical procedure, arrange the following steps in the correct order to determine if this log represents a one-to-one function.
