Answer:

C

Step-by-step explanation:

If you see the same number used as an x-coordinate more than once, it is not a function.

O{(-4,9), (-9,3), (1,7),(-6, 6)}

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

o {(8,-1),(4,-4),(4, -3), (9,5)}  --->   4 is used twice as an x-coordinate

O{(-2,-2), (-1,0), (0, -5),(-9,-5)}

Answer: C
