Answer
Explanation:
Step1: Recall domain definition
The domain of a relation (R={(x,y)}) is the set of all first - elements (x) of the ordered pairs.
Step2: Identify first - elements
For (R = {(-3,-2),(-3,0),(-1,2),(1,2)}), the first - elements of the ordered pairs are (-3), (-3), (-1), and (1).
Answer:
-3, -1, 1
