2. Consider the following table with option prices: If all options have the same maturity date, draw payoff diagrams on a twodimensional plane, as functions of the terminal stock price for the following portfolios, and make sure to clearly mark all non-zero slopes as well as the exact coordinates of all intercepts [ 3 points each]: 2.1. Long 2 calls with K=50, long put with K=75, short 2 calls with K=100. 2.2. Long put with K=50, long (or buy) stock for 75 , and short call with K=120. 2.3. Long put with K=50, short the stock for 100 , short put with K=120. N.B.: In this problem, portfolio compositions are chosen more or less randomly. So you are not expected to get very nice looking graphs
