Which of the sets of ordered pairs represents a function? A = {(2, −2), (5, −5), (−2, 2), (−5, 5)} B = {(4, 2), (4, −2), (9, 3), (9, −3)}

a. Only A
b. Only B
c. Both A and B Incorrect
d. Neither A nor B

a. Only A

Step-by-step explanation:

A = {(2, −2), (5, −5), (−2, 2), (−5, 5)}

B = {(4, 2), (4, −2), (9, 3), (9, −3)}

A is a function, it has a one to one correspondence

B is not a function. The x point 2 goes to 2 different y  values, so it does not have a one to one relationship

a. Only A
