Ineed some serious with this, answer it and not put random things! which of the sets of ordered pairs represents a function? a = {(1, −5), (8, −5), (8, 7), (2, 9)} b = {(7, −4), (7, −2), (6, −3), (−9, 5)} - only a - only b -both a and b -neither a nor b

-Neither A nor B

Step-by-step explanation:

If the "x" value is repeated among the ordered pairs, the relation is not a function.

A: there are 2 instances of (8, _)

B: there are 2 instances of (7, _)

Since both these relations have repeated x values, neither is a function.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

y=x+9

?
