The values are given as 
2005 2.63 
2006 3.26 
2007 3.54 
2008 3.769 
2009 2.13 
2010 2.956 
2011 4.259 
2012 4.16 
2013 3.78 
2014 3.99 
2015 3.10
where left side is the year (x) and right side is the value (y)

The smallest value of y is = 2.13; biggest value is = 4.259 (RANGE)
Domain is (2003 to 2015)

It seems that the equation will not be linear because as the year increases, the value of y is unstable.
