The risk-free rate is 10%. Let f(Si) = 0 if Si 75. (a) Graph y = f(Si). Construct the derivative whose payoff is given by this graph. (b) Use Black-Scholes to price this derivative (c) Assuming Black-Scholes, compute the delta of this derivative. = = = = = Let St be the price of a stock at time t with t O being today.
