Zero property because you are using zeros to multiply
I just started doing function in my Algebra class. So what I was taught was there can't be more than 1 output aka "y" for one input aka "x".
So with the ordered pairs you have above is a function because there's only 1 output coming out. I have a picture showing why. It's labeled a purple one.
You know a graph or anything is not a function because it has more than 1 output which is not okay. For example: (1,6), (5,3), (2,9), and (1, 7) Now you notice that I have two coordinate pairs that have x for 1 and y for 6 and 7. I have another picture showing a example of a non-function.
