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)}​

Respuesta :

Answer:

C

Step-by-step explanation:

In a function, each domain has one range. But a range can have many domains.

Think about it like this:

Patty is eating dinner

Patty is swimming

Both can't happen at the same time.

But:

Patty is eating dinner

Leo is eating dinner

C has two domains of -3, each having different ranges.

Hope that helps, tell me if you need further info. =)

Answer:

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.
