Does a vending machine represent a function and why?

Sure, depending on how the machine is constructed or programmed.

A function can represent any process that takes some input and assigns exactly one output to it. In the case of a simple vending machine, there could one button or sequence of button presses that correspond to the delivery of a certain drink or snack (provided that enough money is fed into the machine first).

A machine that wouldn't qualify as representing a function would be one that consistently offers two or more different drinks.

Answer: See attached.

Step-by-step explanation:

When we have a simple x = a equation, the line will be vertical since all y values of that function/equation are equal to a. In this case, that is 1.

Similar thing for a y = b equation. The line will be horizontal since all x values of that function/equation are equal to b. In this case, that is -5.
