(a) i. Show that if the price elasticity of demand is Q(P) = 419192 then: P Q _ dan(P) Q(P) dP _ dlnP (1)) Functions of the form f (2:) = car" have the same elasticity for any value of I (called const elasticity). However, functions of other forms may have elasticities which depend on the value 0 Find the elasticity of the following: i. f(1) = 5:.."'2 ii. f(1) = 1'2 + 2:: iii. f(.1:) = (13+1)1
