Hello and thank you for your reply. However, the first question was incorrect, for whatever reason. The second question was reset to a different one due to a timeout, I apologize. If you could rework them I would be very grateful..
Find the cost function if the marginal cost function is given by C'(x) = x^(2/5) + 9
Find the demand function for the marginal revenue function. Recall that if no items are sold, the revenue is R'(x) = .09x^2 - .08x + 168

The first question has not changed, but the second has. When inputting the first answer, it was not accepted as correct.
