Question

PLEASE HELP ME



Determine which relation is a function.

{(−5, 1), (−5, 0), (−2, 1), (−1, 4), (6, 2)}
{(−5, 1), (−2, 0), (−2, 2), (3, 4), (6, 2)}
{(−5, 1), (−2, 0), (−1, 1), (2, 4), (6, 3)}
{(−5, 3), (−2, 0), (−1, 2), (6, 4), (6, 3)}

Answer 1

In a function, a given x value can be paired with exactly one y value for that x.

Answer 2

So, in option A,
{(−5, 1), (−5, 0), (−2, 1), (−1, 4), (6, 2)}

-5 is paired to 1 and -5 is also pair to 0. Therefore, Option A is not a function relation..

Answer 3

@cinnnamon Look at the other options and post which one you think is a function, okay?

Answer 4

C? @Directrix

Answer 5

Answer 6

Let me see if the same x is going two different places.

{(−5, 1), (−2, 0), (−1, 1), (2, 4), (6, 3)}

C, I agree.
