Exercise 66 Page 80

To graph an ordered pair ( x, y), start by identifying the x- and y-coordinates on the axes. Then, trace along the grid lines to the point on which both coordinates lie. We will do this for every ordered pair in the relation.

The domain of this relation is the set of all unique x-values and the range is the set of all unique y-values. Using the graph we can write down these values. Domain:& { -2,-1, 0 } Range:& {-2, -1, 1, 2 }
