一道经济类英语高数题.
1.Assuming the function being a total costfunction of a firm find:
- fixed costs of the firm
- stationary points for the function
- use the second order condition to check whether thesestationary points are local extremum points or not; if they are find theextremum type (maximum or minimum)
- at which quantity produced the costs are lowest ifproduction varies over the interval What is the lowestcost?
Where  is the total cost function?
The fixed cost of the firm is the constant including the total cost function.
The stationary pionts for the function is first order detertive equal to zero.
If the second order condition is bigger than zero,the cost has minimum,
If the second order condition is less than zero,the cost has maximum.
If the second order condition is equal to zero,uncetain!
First order condition gives the lowest cost quantity. Plug the quantity back to the total cost function will get the lowest cost!
