Elasticities of Non-Linear Functions

Q_A^D = 3(P_A^-0.33)(P_s^0.8)(P_c^-0.75)(I^1.1)is the demand function for good A,

Where P_A is the own price, P_s is the price of a substitute good, P_c is the price of a complementary good and I is income.

1. What are the 3 price elasticities? Interpret each one.
2. What is the income elasticity? Interpret it.
