 Question 429148: Carbon dioxide is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue, future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The concentration in the year 2000 was greater than it had been at any time in the previous 160,000 years. CO2 sCO2d (a) Let x be in years, where corresponds to 2000, to 2001, and so on. Find values for C and a so that models the data. (b) Graph f and the data in the same viewing rectangle. (c) Use to estimate graphically the year when the carbon dioxide concentration will be double the preindustrial level of 280 ppm.
