Atmospheric carbon dioxide levels continue to increase and are suspected to contribute to global warming. The solution to the polynomial equation:
gives the record high amount of carbon dioxide in parts per million (ppm) in 2005, as measured at Mauna Loa Observatory. Determine this record amount by:
1) Factoring the polynomial (pay attention to how many terms there are to determine how to factor)
2) Solving by setting each factor equal to zero.
3) Evaluating your results to see if they make sense in the context of the question. If a solution doesn't make sense, explain why not.
4) Writing a sentence that gives the labeled solution.
