Consider three demand curves: Q1(P) = 200P^-1, Q2(P) = 200P^-1/2 and Q3(P) = 200P^-2. a) For each demand curve, what is the quantity demanded at P = $1 and P = $1.1? b) Using part a), what are the demand elasticities for the three demand curves between P = $1 and P = $1.1? c) For each demand curve, what is the derivative dQ/dP at P = $1? d) For each demand curve, what is the point elasticity dQ/dP at P = $1?
