Question

23. Cynthia used some of the ordered pairs from the set below to make a new set.

{(4, -3), (-2,5), (5,4), (7,2), (2, -7)}
She wrote the domain of this set as {2,4,5). Which ordered pairs from the origi
make her new set?
O(-2,5), (7,2), (5, 4)
O (5,4), (2, -7), (4, -3)
(2, -7), (4, -3), (-2,5), (5, 4)
O (4,-3), (-2,5), (5,4), (7,2)

Answer 1

B

Explanation:

Cuz Im just right

Answer 2

(5,4), (2, -7), (4, -3)

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
