Compute marginal cost.
1. For the multiproduct cost function C(Q_{1},Q_{2}) = 100 + 2Q_{1}Q_{2} + 4Q_{1}^{2},
Illustrate what is the marginal cost function for good one?
a) MC_{1} = 2Q_{2} + 4Q_{1} - Q_{2}^{2}.
b) MC_{1} = 2Q_{2} + 8Q_{1}.
c) MC_{1} = 100 + 2Q_{1}Q_{2} + 4Q_{1}^{2}.
d) MC_{1} = 4Q_{1}^{2} - 2 Q_{2}^{2}.
2. For the cost function C(Q) = 100 + 2Q + 3Q^{2}, the marginal cost of producing 2 units of output is
