Solve.The price of commodities, like pork bellies, is determined by supply and demand. Thus, the price of pork bellies is a function of the number of pounds of pork bellies produced. The price of a pound of pork bellies can be estimated by the function f(Q) = - 0.000001Q + 0.83, 10,000 ? Q ? 80,000where f(Q) is the price of a pound of pork bellies and Q is the annual number of pounds of pork bellies produced.i) Construct a graph showing the relationship between the number of pounds of pork bellies produced and the price of a pound of pork bellies.ii) Estimate the cost of a pound of pork bellies if 30,000 pounds of pork bellies are produced in a given year.
