the total cost for a company producingAc unit of a product is C(xx) = 0.0001 23- 0.08x2+ 40m+5000 9/ Find the marginal cost function C'(oc) b/ what is the marginal cost when = 500? -/ what is the average cost function C(x) d / what is the marginal average cost function C' Inc) ? e/ what is the marginal average cost function when AC= 500? 6) Find the following for P( nc) = 023 - 12 nc a all critical points with (x,y ) coordinates b/ the intervals where Plac) is increasing and decreasing use a sign diagram of label each critical point as a relative maximum or minimum. 7) Find the following for P( x) = 203 - 302+ 2 0C+ 1 the coordinates (,y) of any inflection points. the intervals where the graph of floc) is concave upward and concave down would. Hint : use a diagram
