Assume the following market demand and supply functions
P + 25
Qd = 1000 P2 + 5
Qs = 100 P0.4
(a) Graph the excess supply function.
(b) Use the Taylor expansion of the excess supply function and find the first degree approximation for the market equilibrium price and quantity.
(c) Write the linear expansion of the demand and supply functions separately and then solve the linear system for the market equilibrium price and quantity. Compare your results with those from part (b).
