4. Hybrid Automobiles. In 2004, only 84,199 hybrid automobiles were sold, while in 2012, 431,798 were sold (Source: U.S. Department of Transportation). The quartic function
where x is the number of years after 2004, can be used to estimate the number of hybrid automobiles sold in years 2004 to 2012. Use this function to estimate the number of hybrid automobiles sold in 2008 and in 2011.
