May I ask then why a student needs to see this graph from a GC?
They are better off spending time on other more useful "every day"
Activities such as "cooking", "lawn mowing" ....., or do more arithmetic that they still not good at. At least, they will know when the cashier in the store punches the wrong key! In addition, they save their parents some money from not buying those GC which they will never use after graduation! (as you said that they will not!)

I have to ask--why would a student _want_ to graph those or know what they
look like? How do graphs with X and Y connect to what people do every day
if they are not mathematicians?
