1. Find the Inverse and Graph the Functions

2. Find an Inverse Relation
The ordered pairs of a relation are… {(1, 3), (6, 3), (6, 0), (1, 0)} Find the inverse of this relation.
To find the inverse of this relation, reverse the coordinates of the ordered pairs.
The inverse of the relation is {(3, 1), (3, 6), (0, 6), (0, 1)}.
Example 1

3. GEOMETRY The ordered pairs of the relation {(–3, 4), (–1, 5), (2, 3), (1, 1), (–2, 1)} are the coordinates of the vertices of a pentagon. What is the inverse of this relation?
A. cannot be determined
B. {(–3, 4), (–1, 5), (2, 3), (1, –2)}
C. {(–3, 4), (–1, 5), (2, 3), (1, 1), (–2, 1)}
D. {(4, –3), (5, –1), (3, 2), (1, 1), (1, –2)}
