Question

(04.01)

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

The correct option is (C) (-4, 5).

Explanation:

Answer 2

To be a function each input (x value) should have one output value (y)

There is a point (-4,3) then there is another point with -4 that has a y value of 5 but the next point in line with x of 9 also has a y value of 5

so you should remove (-4,5)

answer: (-4 5)
