For a cost function C 50 2Q Q2 the marginal cost of produ

For a cost function C = 50 + 2Q + Q², the marginal cost of producing 2 units of output is: 50, 8, 58, None of the above

Solution

Cost function (C) = 50 + 2Q + Q2

   C = 50 + 2 * 2 + 2 * 2 [ When Q = 2 ]

   C = 50 + 4 + 4

   C = 58

Conclusion:- The marginal cost of producing 2 units of output is 58
