Scientists can estimate the increase in carbon dioxide in the atmosphere by measuring increases in carbon emissions. In 1998 the annual carbon emission was about eight gigatons (a gigaton is a billion metric tons). Over the last several years, annual carbon emission has been increasing by about one percent. Homework Help ✎

  1. At this rate, how much carbon was predicted to be emitted in 2010?

    What multiplier will you use for something that is increasing by 1%?

  2. Write a function, , to represent the amount of carbon emitted in any year starting with the year 2000.

    You can either calculate the begining amount for 2000 and let time = x or
    you can let the beginning amount be the same as in 1998 and let time = x + 2.
