Given a demand function Q = f(P) the own price elasticity of demand is dened as hem) What is the own price elasticity of demand a (a) for the linear demand function Q = 100 5? when P 2 10. (b) for the linear inverse demand function P = 100 462 when (i) Q = 10 ; (ii) Q = 20 ; (iii) Q : 12.50 . {c} for the demand function Q : P415, when (i) Q: 100;(ii)Q=20. (d) for the inverse demand function P = 5Q"1 , when (i) Q : 10; (in Q : 20
