1. Find a function f and a constant c such that for all x >06+i (t) t2 film dt =2/6=2V 2. The marginal average cost of producing r items of a certain commodity is given by the function -2 C'(x)=-1000x-2=2 If the average cost for producing 100 items is $25, find the total cost function. To get full credit, you should find some antiderivative first.
