Question

PLEASE PLEASE HELP

The group of points {(0, 1), (0, 5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2, 7), (3, 1), (5, 7)} is a function. What do you notice about the two groups of points? What do you think it means to be a function?

Answer 1

I think to be a function is when you have to groups of something or if it's an number it can be an even number or an odd number you just have to find out what it is.
