Functions are relations that derive one output for each input, or that is the technical definition for it, or one Y value for any X value inserted into the equation. A function is made by a set of ordered pairs. examples of ordered pairs are (4,7) as 4 is the X value and Y is the Y value.
Its quite simple to see if a function is or is not a function. Here is an example
[(4,7),(6,9),(4,1),(9,0)] is not a function because when you look at all the x values which are 4,6,4, and 9, you see that the #4 is repeated signalling that It it not a function.
[(2,3),(9,3),(1,6),(8,2)] is a function, lets check it. All the x values are 2,9,1, and 8, and as you can tell, none of them are the same.
