Answer:
The domain of a relation is the set of all the x-terms of the relation.
If an x-term appears twice in a relation, only list in once in the domain
The x-values for those three ordered pairs are 2, -2, and -2. For the first ordered pair, you move two positive units along the x-axis, and then along the y-axis to -11. For the second ordered pair, you first move two negative units on the x-axis to -2, and then 11 positive units on the y-axis
