Question

Which set of ordered pairs represents a function?

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

Answer 1

The final set of ordered pairs represents a function.

Explanation:

Each X value corresponds to exactly one y- value. Essentially, none of the x values are the same in the final set.
