Which set of ordered pairs is a function?

• {(9,5) , (10,5) , (9,-5) , (10,-5)}

• {(3,4) , (4,-3) , (7,4) , (3, 8)}

• {(6,-5) , (7, -3) , (8, -1) , (9, 1)}

• {(2 , -2) , (5, 9) , (5, -7) , (1, 4)}

Is the relation a function? Why.

• YES, because the x-value 11 has two y-values pair with it.

• YES, because each x-value (input) has exactly one y-value (output) paired with it.

• NO, because the x-value 11 has two y-values (outputs) paired with it.

• SOMETIMES, because each x-value has only one y-value paired with it.
