Which of the relations given by the following sets of ordered pairs is not a function?
a. {(52)}{(52)}
b. {(−4,−−1,−,,,10)}{(−4,−−1,−,,,10)}< br /> c. {(−8,−−6,−−4,−−2,−−1,−4)}{(−8,−−6,− −4,−−2,−−1,−4)}
d. {(−6,−3,−,,−,3)}

The answer is the B)

Step-by-step explanation:

By the definition, in a function, a value in the first set of numbers only have a value in the second set of numbers, so for every pair of numbers, we have to review if the first number for this pair only appears one time in all the function.

All the set ot values agrees with this definition except the B, because the third and fourth pair have the same first value (3)

final answer is : )

its the fourth option
