Public Management—NEH Funding: The National Endowment for the Humanities (NEH) is an independent grant-making agency of the U.S. federal government used to support research, education, and public programs in the humanities. The annual amount in federal research grants to the NEH from 1990 to 2010 can be modeled by the rational function

where x represents the number of years since 1990, and f(x) represents the amount in federal research grants to the NEH, measured in millions of dollars. (Source: U.S. National Endowment for the Humanities). Approximate the instantaneous rate of change of f when x = 7 and interpret.
