+ -/4 points HarMathAP12 2.4.045.0/15 Submissions Used Suppose that the cost C (in dollars) of removing P percent of the particulate pollution from the smokestacks of an industrial plant is given by 7600p C(O) = 100-P (a) Is C) undefined at any p-value? If so, what value? (If an answer does not exist, enter DNE.) p= (b) What is the domain of cp) as given by the equation? (Enter your answer using interval notation.) (c) What is the domain of C() 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 increases (bounded by 7600) as p increases. The cost remains constant as p increases. The cost decreases without bound as p increases. The cost increases without bound as p increases. The cost decreases (bounded by 0) as p increases.

Answer 1

c(P) = 7600p 100-p a) Yes mod clp) is when undefined denominator =0 100-pao p=100

b) Domain PE (-00, 100) u (100,00) According to problem pe [o, 100) when p reaches 100% The cost increases without bound. as p increases
