    Green House Gases. Carbon Dioxide CO2 is a green house gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels in 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 CO2 concentration in the year 2000 was greater than it had been at any time in the previous 160,000 years.

    Year 2000 2050 2100 2150 2200
    CO2 (ppm) 364 467 600 769 987

    (a) Let x be in years, where x = 0 corresponds to 2000, x = 1 to 2001, and so on. Find the values for C and (a) so that f(x) = Ca^x models the data.

    (b) Graph f and the data in the same viewing rectangle.

    (c) Use f(x) to estimate graphically the year when the carbon dioxide concentration will be double the preindustrial level of 280 ppm.
