Which set of ordered pairs in the form (x,y) does not represent a function of x? A.{(-1,2), (3,-2), (0,1), (5,2)} B.{(-1,2), (3,2), (-2,2), (0,2)} C.{(-1,2),(3,-2),(0,1),(3,5)} D.{(-1,2),(2,3,)(3,-2),(-2,0)}

Answer 1

(C.) this is because the 3 in the output belongs to both -2 and 5. This is not a function.

Thank you.
