C(n)=1000+33x-9x^2+x^3
find (a) the level of production at which the marginal cost is a minimum, and (b) the
minimum marginal cost.
2.for th price function given by p(x)= (800/(x+3))-3
find the number of units x1 that makes the total revenue a maximum and state the
maximum possible revenue. What is the marginal revenue when the optimum number of
units,x1, is sold?
