2. Model the somewhat mysterious process of energy transformation using a state machine model. Your model should at least include the following 3 items: (a) A description the state of SFC's two main energy quantities as a set. Make sure to express what set(s) your state's values come from. (b) At the beginning of SFC, there were two initial quantities for b and r. Considering this, symbolize the start state of your model. (c) Define the energy transitions as functions on the states of your model.
