Answer:
3) 2
4) 5.5
5) [2008, 2010]
6) [2010, 2013]
7) (5.5 - 2)/(2010 - 2008) = 3.5/2 =
1.75 million/year
8) 2008-2010: 1.75 million/year
2008-2013: (3.1 - 2)/(2013 - 2008)
= 1.1/5 = .22 million/year
The average rate of change from
2008 to 2010 is greater than the
average rate of change from
2008 to 2013.
