You can put this solution on YOUR website! mapping is writing the x and y in a column and drawing arrows from x to y based on the ordered pair.
When there are two values of y for the same x (a circle), it is not a function.
So all you have to do is see if the x-values are all different. If they are, it is a function. If not, they have to have the same y (same ordered pair) to be a function.
Here, all the x values are different. It is a function.
