Domain and Range of an Inverse Function

Example: Finding the Inverse of the Function {(0,3),(1,5),(2,7),(3,9)}

Inverse Function Notation

Example: Finding the Inverse of the Function {(0, 4), (1, 7), (2, 10), (3, 13)}

Finding an Inverse Function Using an Algebraic Equation

A company directory uses a function $f$ to map employee badge numbers to their assigned office room numbers: f = {(1050, 12), (2100, 14), (3150, 16)}. To create a reverse lookup that finds a badge number based on a room number, the system uses the inverse function $f^{-1}$. Which of the following represents the set of ordered pairs for $f^{-1}$?

An HR database uses a one-to-one function to map an employee's starting year ($x$) to their earned vacation days ($y$), written as the ordered pair (x, y). To define the inverse function that maps vacation days back to the starting year, you must form new ordered pairs by ________ the $x$- and $y$-coordinates of each original pair.

Retail Inventory Reverse Lookup

In a company's asset management database, a one-to-one function is used to link unique hardware tags to specific office workstations. Match each original assignment pair (Hardware Tag, Workstation ID) with its corresponding inverse pair (Workstation ID, Hardware Tag) used for reverse-lookup audits.

A corporate security system uses a function to map unique employee identification numbers ($x$) to their designated office security codes ($y$) using the set of ordered pairs (x, y). To define the inverse function $f^{-1}$, which identifies an employee identification number when given a security code, you must reverse each ordered pair to (y, x).

Generating a Reverse Lookup Directory

An inventory clerk at a fulfillment center uses a database represented as a set of ordered pairs (x, y), where $x$ is a unique bin location and $y$ is an item barcode ID. To set up a reverse-lookup query (finding the bin location from a barcode), the clerk must find the inverse function. Arrange the steps in the correct order to construct the inverse function from the original set of ordered pairs.
