Which ordered pairs match the mapping diagram?


a. (1, 0), (7, 2), (3, 4), (−1, 1), (−7, −6)


b. (0, 1), (2, 7), (3, 4), (−4, 1), (−6, 7)


c. (0, 1), (0, 4), (0, 7), (2, 7), (−6, 7)



d. (0, −1), (2, −7), (−3, 4), (4, 1), (6, 7)

The correct answer is B. (0, 1), (2, 7), (3, 4), (−4, 1), (−6, 7)

This is because we need to follow each line and make an ordered pair from it. You'll first see that the 0 on the left is connected to the 1 on the right. This will give up (0, 1) and narrow our choices down to B and C. You'll also see that 0 is connected with no other number, which eliminates C, leaving us B as the correct answer.

the answer will be
