MARGINALANALYSIS The profit obtained from producing x thousand units of a particular commodity each year is P(x) dollars, where

a. Find the marginal profit P'(x), and determine all values of x such that P'(x) = 0.

b. Sketch the graph of marginal profit along with the graph of P(x) on the same coordinate plane.

c. Find P"(x), and determine all values of x such that P"(x) = 0. How are these levels of production related to the graph of marginal profit?
