What sets of ordered pairs represents a function ? a={(2,-2), (5,-5) (-2,,5)} b={(4,2), (4,-2) , (9,3) (9,-3)}

A

Step-by-step explanation:

In a function, one x value (the number in front) goes to one y value.

In {(4, 2), (4, -2)}, the x value 4 goes to two y values (2 and -2), which lets you know it’s not a function.
