Question

Which order pair could you remove to make this a function?

(1, 3) (5, 0), (5, 3), (4, 0), (3, 3)

Answer 1

Answer: (5,0)

Explanation:

You could remove this one, because for each input (x) there can only be 1 output (y)

So by removing (5,0) this becomes a function. 5 only has one output now, (3)
