A multiproduct firm's cost function was recently estimated as C(Q_{1},Q_{2}) = 2 + 7Q_{1}*Q_{2} + 3Q_{1} ^ 2 + 4Q_{2} ^ 2 What is the cost of producing Q_{1} = 1 , Q 2 =0? What is the cost of producing Q_{1} = 0, Q_{2} = 1 ? What is the cost of producing Q 1 =1,Q 2 =1? Are there economies of scope in producing 1 unit of product 1 and 1 unit of product 2? What is the marginal cost of producing Q_{1} at 1, Q 2 =0? ?? What is the marginal cost of producing Q_{1} at Q_{1} = 1; Q_{2} = 1 ? Are there cost complementarities in producing products 1 and 2
