Solve.
-Computer sales in the United States have increased since 1992. The polynomial 0 $0.059 x ^ { 2 } + 0.69 x + 4.5$ can can be used to approximate the number of computer sales during the years 1990-2000 where x is the number of years after 1990 and the value of the polynomial is the computer sales (in millions). Use the function to predict the number Of computers sold in 2001. Round the answer to the nearest tenth of a million.
A)12.7 million computers
B)17.3 million computers
C)19.2 million computers
D)21.3 million computers

To predict the number of computers sold in 2001, substitute x = 11 (since 2001 is 11 years after 1990) into the polynomial: $0.059(11)^2 + 0.69(11) + 4.5$. This calculation results in approximately 19.2 million computers.
