  • Note, you can solve for the roots of this polynomial even though it is degree 4 by solving for x^2 using the quadratic formula and then taking the positive and negative square roots of each of these numbers. However, you must check which are real numbers and which are not.
• #6. Assigned - Wed. Mar. 21 (Due Fri. Mar. 23)
  • 2.7 #14
  • This problem looks complicated but it isn't, the main fact is that R(x)= xp where p is the price/demand function. After that, the profit function is, as always, P(x)=R(x)-C(x). In part (c) the production level is a function of the tax 'T' and so it enters into the calculation to optimize the profit. The tax revenue the government then recieves comes from this as well.
