The total revenue function for a product is given by R=410x dollars, and the total cost function for this same product is given by C = 7000+40x + x2, where C is measured in dollars. For both functions, the input x is the number of units produced and sold. a. Form the profit function for this product from the two given functions. b. What is the profit when 11 units are produced and sold? c. What is the profit when 27 units are produced and sold? d. How many units must be sold to break even on this product? a. Write the profit function. P(x) = x²+370x-7000 (Simplify your answer.) b. When 11 units are produced and sold, there is a loss (Simplify your answer.) of $
