C.
(8, –2), (–2, 5), (6, 0)

D.
(–2, 3), (–5, 9), (–5, 3)

Answer 1

In coordinate pairs if the \(x\) repeats, the relationship is NOT a function.

\((1, 0)\), \((2, 0)\), \((3, 0)\) = \(\textbf{Relationship is a function.}\)
\((1, 0)\), \((2, 0)\), \((2, 0)\) = \(\textbf{Relationship is NOT function.}\)
