Answer:
D
Explanation:
If the cost function C is continuous and differentiable, the marginal cost MC is the first derivative of the cost function with respect to the output quantity Q:
MC(Q)= dC/ dQ.
The marginal cost can be a function of quantity if the cost function is non-linear. If the cost function is not differentiable, the marginal cost can be expressed as follows:
MC=^C/^Q
where ^ denotes an incremental change of one unit.
Answer:
Option "B" is correct.
Explanation:
It is the change in total cost, not total variable cost over the output. Thank you.
