The national defense budget expenses V (in billions of dollars) for veterans in the United States from 1990 to 2005 can be approximated by the model
*Picture of model included*
where t represents the year, with t = 0 corresponding to 1990. Use the model to find total veteran expenses in 1999.
How can we find the average rate of change in this case?
