C (x) =72000 +60x R (x) =200x-x^2/30 find the profit function,level of production that will maximize the profit,the maximum profit.
Yes,Sheg.. First one is Cost function,second one is Revenue function..
i don't know..this question comes from my math's lecturer.. can you help me?
ok Profit = Revenue - Cost
can you show me the steps to answer this question?
yeah i can just subtract cost function from the revenue function
Sheg,i still have a lot of math question need your help.. Can i ask here too?
hey this question is still not complete
okay,i ask you later.. thanks you..=)
Take the derivative of of profit, set the derivative equal to zero then do an increasing decreasing test to see whether or not you got a max or a min, usually it will be a max anyways but its always good to show your work
the roots of the function will be the max or the min
also that x value you find is the level of production
