The table gives methane gas emissions in
millions of metric tons. The quadratic model
y = 0.0429x² - 9.73x + 706 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. Complete parts a and b.
