To find: The estimated population in 2008 by the given data.
The estimated population in 2008 is 1,096.88.
Given information: A data is given.
Year | 2004 | 2007 | 2009 | 2010 |
Population | 457 | 910 | 1244 | 1315 |
Concept used: Polynomial functions can be constant, linear, quadratic, cubic and so on. Graphing calculator can be used to determine functions that model data.
Calculation:
Using the graphing calculator, list the data values from the table. Let
Using the Cubic Reg function, the quadratic model for the data values is:
Using the cubic model, estimate the population in 2008. Let $x=8$ for 2008.
The estimated population in 2008 is 1,096.88.
