A firm's total revenue function takes the form cQ2 + dQ. It is known that TR = 402 when Q = 3 and TR = 1098 when Q = 9. (a) Show that this information may be expressed as Ax = b where x = [c, d]¹, b = [402, 1098] and A is a 2x2 matrix which should be stated. (b) Use the matrix inverse method to work out the values of c and d, and hence write down the demand equation. (a) The coefficient matrix is (b) c= -2, d = 140 and the demand equation is P=Q+
