The daily marginal revenue function associated with selling x widgets is given by R'(x) - 6x2 + 16x + 15 where R'(x) is measured in dollars per unit per day and x denotes the number of widgets produced and sold. (a) Determine the revenue function, R(x), associated with producing and selling x widgets. R(x) - (b) Determine the demand function relating unit price, p(x), to the quantity demanded, x. p(x) [-11 Points] DETAILS Math 110 Course Resources - Indefinite Integrals Course Packet on antiderivatives Determine whether each statement is true or false.
