Implicit Differentiaion & Related Rates Course Packet on computing elasticity of demand using implicit differentiation The demand function for SkanDisc 2GB thumb drives is given by P = 4(x + 3) e-x/3 where p is the wholesale unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. Compute the price, p, when x = 9. Do not round your answer. Price, P dollars Use implicit differentiation to compute the rate of change of demand with respect to price, p, when x = 9. Do not round your answer. Rate of change of demand, x' = thousands of units per dollar Compute the elasticity of demand when x = 9. Do not round your answer, Elasticity of Demand =
