Parts I, II \& III: Suppose that the cost function for a product is given by C(q)=q2+8q+10 The demand function for product is q=4p+300. Part I 1. Develop the total revenue, total cost (if not given), and profit functions. Explain these functions in few sentences. 2. Develop a 2D plot for demand versus the price. What do you notice? 3. Develop a 2D plot for total cost versus the quantity; average cost versus the quantity; marginal cost versus the quantity; and marginal revenue versus quantity on the same graph. What do you notice
