Problem: The Dijon Company's total variable cost function is:
TVC = 50Q -10Q^2 + Q^3
where Q is the number of units of output produced.
1. What is the output level where marginal cost is at minimum?
2. What is output level where average variable cost is a minimum?
3. What is the value of average variable cost and marginal cost at the output specified in the answer to part 2?
