This is considered a function because each input has a different output. For example, a certain x value doesnt equal 2 different y values, making this a function. Take this: if there is (2,4) and (3,4), this is a function because although the y values are the same, the x values are different. (2,3) and (2,4) do not convey a function because the x values are the same, but each has a different y value.
