Question

Which set of ordered pairs does not represent a function?O {(4,6), (9,–2), (3, -5), (6,6)}O{(-1, -2), (-4,9), (8, -9), (1, 2)}O{(-1,9), (-7,8),(3,-1), (4, -1)}O {(2, 2), (0, -8), (2,7), (-3,8)}

Answer 1

A function can return a unique value (y) for an input value x.

The ordered pairs are in the form (x,y)

In the last set, we can see that

(2,-2) and (2,7)

The input value 2 gives 2 different output values (-2 and 7)

Therefore, that set doesn't represent a function.

Correct option: {(2, 2), (0, -8), (2,7), (-3,8)}
