Using the cartesian diagram below, determine the relation .
A relation from to is a set of ordered pairs .
In a Cartesian diagram, each point corresponds to an ordered pair where:
In this Cartesian diagram, there are 3 points, so there are 3 ordered pairs in .
The lowest point has an -coordinate of and a -coordinate of 3, so .
The middle point has an -coordinate of 2 and a -coordinate of 7, so .
The highest point has an -coordinate of 6 and a -coordinate of 11, so
