Which relation is a function?

the second option

Step-by-step explanation:

The second one is the function.

Explanation:

In the first one is (4,-2), (-1,3), (-5,-2), (3,3), and (3,7) this would not be a function because there are two of the same numbers in the X- intercept.

It will look like this (X,Y)

The second one is (4,-2), (-1,3), (-5,-2), and (3,7). This is not like the first one which makes it a function. It doesn't matter if you have two or more of the same numbers in the Y- intercept.

The third one is just like the the first one.

What helps me is writing them down like i did for the first and second choice.

Hope this helps. Have a nice day.
