The value (in millions of dollars) of electric household ranges and ovens shipped in the United States can be approximated by the function
g(x) = −21.1x2 + 205x + 2164,
where x = 0 corresponds to the year 2000. (Data from: U.S. Census Bureau.)
(a) What is the value of the ranges and ovens shipped in 2001?
(b) What is the value of the ranges and ovens shipped in 2009?
