Poverty Level From 2005 through 2013, the population p (in millions) living below poverty in the United States can be modeled by
(a) Use a graphing utility to graph the model on the interval
(b) Use the second derivative to determine the concavity of the graph of p.
(c) Find the point(s) of inflection of the graph of p.
(d) Interpret the meaning of the point(s) of inflection from part (c).
