PC Connection and CDW are two online retaliers that compete in an internet market for digital cameras. While the products they sel are similar, the firms attempt to differentiate themselves through their service policies Over the last couple of months, PC Connection has matched COW's price cuts, but has not matched its.price increases. Suppose that when PC Connection matches CDW's price changes, the inverse demand curve for CDW's cameras is given by P=2,0004Q When it does not match price changes. CDW: inverse demand curve is P=1,8600.50. Based on this informaton, determine CDW's inverse demand function over the last couple of months Over what range wil changes in marginal cost have no effect on CDW's profit-maximizing levet af output? $to$
