I am working on a extra credit project for Microeconomic theory and I really need to do well. The project is to write-up an in-depth analysis of the firm using the knowledge and applications learned in this class.There are several parts of the project starting with type of business-- oligopoly, then company background, competitors, market share, demand, supply, products, etc. Right now I am working on the demand part- all that is stated for this part is asking for "Product demand and demand functions (and curves)" and I am not sure if I've been working so long that I am overthinking the explanation and curves. Any guidance on how I should get a start on this demand part so I can continue my work flow would be great.
