The marginal cost function C'(x) was defined to be the derivative of the cost function. (See Sections 3.7 and 4.7) The marginal cost of producing gallons of orange juice is C'(x) = 0.82 - 0.00003x + 0.000000003x2(measured in dollars per gallon). The fixed start-up cost is C(0) = $18,000.Use the Net Change Theorem to find the cost of producing the first 4000 gallons of juice.
