Answer:
(5,4), (2, -7), (4, -3)
Step-by-step explanation:
The first option is (-2,5), (7,2), (5, 4).
The domain for this pair of ordered pairs is {-2,5,7}
The second set is (5,4), (2, -7), (4, -3)
The domain is {2,4,5}
The third set is (2, -7), (4, -3), (-2,5), (5, 4)
The domain is {-2,2,4,5}
The fourth set is (4,-3), (-2,5), (5,4), (7,2)
The domain is {-2,4,5,7}
Therefore the correct choice is the second option
