To Find: The 4 -year period that has the greatest rate of change, without calculating, then calculate to verify answer.
Answer to Problem 2GP
2007-2011 year period has the greatest rate of change.
Explanation of Solution
Given information: Graph is given in below figure.
Calculation:
From the graph the section of the graph for 2007-2011 is steepest so ,2007-2011 year period has the greatest rate of change.
Rate of change for 2003-2007:
Rate of change for 2007-2011:
Rate of change for 2011-2015:
From the calculation it is also clear that 2007-2011 year period has the greatest rate of change 2.44 because in 2003-2007 year period rate of change is 2.2 and in 2011-2015 year period rate of change is 2.33 .
