Math Problem Statement
The following table gives the millions of metric tons of carbon dioxide emissions in a certain country for selected years from 2010 and projected to 2032. Year 2010 2012 2014 2016 2018 2020 CO2 Emissions 338.5 361.5 399.1 422.8 452.1 498.4 Year 2022 2024 2026 2028 2030 2032 CO2 Emissions 559.2 590.9 629.7 663.1 703.1 742.7 (a) Create a linear function that models these data, with x as the number of years past 2010 and y as the millions of metric tons of carbon dioxide emissions. (Round all numerical values to two decimal places.) y(x) =
