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)}

(–5, 6)
(1, 0)
(–4, 5)
(9, 5)

Answer 1

The answer is (-4,5) which is C

I hope this is helpful xD :)

Answer 2

For a set to be a function, there can be no repeating x-values. Therefore, the answer is (-4,5), because the input value "-4" has two different output values.
