Hello,
Domain is represented by the x coordinate and range is the y coordinate.
Let's say you are in a swimming pool. The deeper you go the more pressure
will be on your ears, right?
So let's say you go 1 foot down and you have 2 pounds of pressure on your ears.
Then you go down 2 feet and have 4 pounds of pressure. (These are just numbers assign, not actual pressure)
We could have the x coordinate represent feet and y be the amount of pressure.
This could then be graphed.
Make sense?
