This lesson focuses on finding inverse functions and their graphs. Students begin by using inverse operations to isolate the variable and solve an equation. They then find the input of a function that gives a certain output. Next, they identify the inverse function (reversing the mapping) for various linear functions, as well as finding the inverse of the general linear equation y = ax + b by exchanging the variables and solving for y. They proceed to identify and graph linear functions and their inverses on the same coordinate grid.
