Answer:
For table C, there is no x-value that has more than one y-value.
Step-by-step explanation:
A function must not have the same first coordinate which is the x-coordinate having more than y-values. So that it can pass the vertical line test.
For table A, we have [tex](0,-4),(0,4)[/tex].
Since there is at least an x-value having more than one y-value, it ceases to be a function.
For table B, we have [tex](5,-1),(5,3)[/tex].
Since there is at least an x-value having more than one y-value, it ceases to be a function.
For table C, there is no x-value that has more than one y-value.
For table D, we have [tex](-2,1),(-2,-3)[/tex] and [tex](2,1),(2,-3)[/tex]
Since there is at least an x-value having more than one y-value, it ceases to be a function.
