Question

Which point could be removed in order to make the relation a function? {(–4, 3), (–5, 6), (1, 0), (–4, 5), (9, 5), (0, –7)}

Answer 1

When there are two equivalent x values, the table cannot produce a function, so you would have to remove (-4,3) or (-4,5) because they have the same x values.
