The demand function for a certain brand of compact discs is given by p=−3x 2 −2x+20 where p is the wholesale unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. (a) Compute the price, p, when x=2. Price, p= dollars (b) Use implicit differentiation to compute the rate of change of demand with respect to price, p, when x=2. Do not round your answer. Rate of change of demand, x ′ = thousands of units Elasticity of Demand = 33/1
