Suppose that the cost C (in dollars) of removing p percent of the particulate pollution from the smokestacks of an industrial plant is given byC(p) =6400p100 - P(a) Is C(p) undefined at any p-value? If so, what value? (If an answer does not exist, enter DNE.)p=(b) What is the domain of C(p) as given by the equation? (Enter your answer using interval notation.)(c) What is the domain of C(p) in the context of the application? (Enter your answer using interval notation.)(d) What happens to the cost as the percent of pollution removed approaches 100%?The cost decreases without bound as p increases.The cost decreases (bounded by 0) as p increases.The cost increases (bounded by 6400) as p increases.The cost remains constant as p increases.The cost increases without bound as p increases.Need Help?Read It
