Question

Which set of ordered pairs represents a function?

O {(7,4), (3,8),(-4,-4),(0,4)}
O {(-5,1),(3, -7), (2,-4), (2,7)}
O {(-8,0), (-5,6), (-8,1),(-6,5)}
O {(4,2),(4, -9),(-9,-6), (7,1)}

Answer 1

{(7,4), (3,8), (-4,-4), (0,4)}

Explanation:

A function does not have reoccurring x values that are identical in its points. You can have reoccurring y values in a function (ex y=sin(x)).
