Learning about functions

The video uses a vending machine analogy to explain the concept of functions. It describes how pressing a button (input) should result in receiving the desired soda (output). If the machine dispenses a different soda, it is not functioning correctly, illustrating a non-function. The video emphasizes that a function should always produce a unique output for a given input.
