Ill give brainliest answer in 5 minwhich of the sets of ordered pairs represents a function? a = {(−5, 5), (−2, 2), (2, −2), (5, −5)}b = {(4, 2), (3, −2), (9, 4), (11, −3)}select one: a. only ab. only bc. both a and bd. neither a nor b

D.

Step-by-step explanation:

Function does not have duplication of a number.be

The A choice contains duplicates of both 2 and -2.

The B choice contains a duplicate of 4.

Therefor, it must be D.

Which of the sets of ordered pairs represents a function?  

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

B = {(4, 2), (3, −2), (9, 4), (11, −3)}

Select one:

a. Only A

b. Only B

c. Both A and B

d. Neither A nor B

the answer is c. 23/3

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
