Which set of ordered pairs does not represent a function? A{(-8,0),(4,0),(5,-2), (7,-9)}
B{(-6,0), (-4,2), (4,0), (-1,-9)}
C{(6,-9),(-3,6),(-3,-7),(-9, -2)}
D{(5,-6), (0,5), (-4, -8), (1, -8)}

C. C{(6,-9),(-3,6),(-3,-7),(-9, -2)}

Step-by-step explanation:

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

Here, you only see this in choice C, where x = -3 for two points. That makes this relation not a function.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
