AA Section 8-2
This document discusses inverses of relations. It defines an inverse as the relationship obtained by reversing the order of coordinates in each ordered pair. An example shows how to find the inverse of a relation and determine if the original relation and inverse are functions. The inverse relation theorem states that the inverse can be found by switching x and y, the graph of the inverse is a reflection over y=x, and the domain of the inverse is the range of the original and vice versa. Another example shows finding the inverse of a function and graphing both. The horizontal line test is introduced to determine if an inverse is a function. Homework problems are assigned.
