Which of the sets of ordered pairs represents a
function? **easy** BRAINLIEST
A= {(2,-2). (5, -5), (-2, 2), (-5, 5)}
B = {(4, 2), (4, -2). (9, 3), (9, -3)}

O Only A
O Only B
O Both A and B
O Neither A nor B​

A function means that “for only x, there is one and only one y”. If you look at these sets, you can see that the statement is true for A, but not for B. In B, you can see that an x-value of 4 has two y-values (2 and -2) and a value of 9 also has two y-values. Therefore, only A is a function.
A is a set with ordered pairs. This is because for a function to work there can not be a multiple of an input number. So only A would work since there is no input number that is repeated. Hope this helps and if you could please consider marking me the brainliest, thank you!
