Methane Gas Emissions The table gives methane gas emissions from all sources in the United States, in millions of metric tons. The quadratic model
approximates the emissions for these years. In the model, x represents the number of years since 2008,
so x = 0 represents 2008, x = 1 represents 2009, and so on.
(a) According to the model, what would emissions be in 2014? Round to the nearest tenth of a million metric tons.
(b) Find the nearest year beyond 2008 for which this model predicts that emissions will reach 500 million metric tons.
