After door-to door canvassing, census workers determine the number of unoccupied homes. The table below lists the number of homes, in millions that were unoccupied in four census years.
Year, x Number of Unoccupied Homes in Census (in millions)
1980, 0 .................................. 5.8
1990, 10 ................................ 7.3
2000, 20 ................................ 9.9
2010, 30 ............................... 14.3
a) Use a graphing calculator to fit an exponential function to the data, where x is the number of years after 1980.
b) Graph the function found in part (a).
c) Use the function found in part (a) to project the number of unoccupied homes in the 2020 Census. |
