      I think Alex is complicating this a bit much.

      As far as I'm aware, you fully understand functions, just not how to graph them.

      Well, it's pretty easy once you know that:

      x = your input.

      y = your output.

      so say your x = 4. Then on the X Line, you are +4 across.

      Input: 4

      Function: x + 1

      Output: 5

      So the x value is 4 and the y value is 5. You can now graph your line. As Alex said, there will be much more complex types of functions where x will be squared and this will give you a parabola.
