Question

Which set of ordered pairs does not represent a function?

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

Answer 1

The first one and the third set because the number 8 brackets appears with 4 and -6. Inorder to be a function the y values must be unique. The third set -2 repeats itself
