the answer is C

Answer 2

C

Explanation:

A function is when the x value has ITS OWN Y VALUE, so the x value can't have more than one y value.

Can't be A, because 6 and 13 both have 10

Can't be B, because there are two x - values (6 and 6)

It can only be C, because each x-value has a different y-value
