Question:
Environmentalists have estimated that the average level of carbon monoxide in the air is L(n) = (1 +
0.6n) parts per million (ppm) when the number of people is n thousand. Assuming that the population in thousands at time t is n(t) = 400 + 30t + 0.15t2,
(a) express the level of carbon monoxide in the air as a function of time and
(b) estimate the level of carbon monoxide at t = 5.
(a) Setting up the composite function L[n(t)] by substituting n(t) for each occurrence of n in L(n), we have
