A preliminary sketch to work out how to model a vending machine in GeoGebra. I'd love any feedback!
I might try enlarging this to be a better model. The idea is to relate the function concept to a vending machine. The first machine is a function with inputs A1, B1, A2, B2, and the 2nd is not a function. Input "SODA" gets whatever is next.
Any suggestions?
