1st relation: The points on the coordinate plane have coordinates (-3,-4), (-3,1), (-1,1), (1,-1), (4,4).
The domain of this relation is {-3,-1,1,4} (take x-coordinates of each ordered pair).
The range of this relation is {-4,-1,1,4} (take y-coordinates of each ordered pair).
Answer: correct choice is 3.
2nd relation: Similarly,
the domain is {-4,-3,1} (take x-coordinates of each ordered pair)
and the range is {1,3,4} (take y-coordinates of each ordered pair).
Answer: correct choice is 2.
