The accompanying graph shows the median income in
U.S. households (adjusted for inflation) between 1990 and 2005. Use the graph to answer the following questions, making reasonable approximations where needed.
(a) When was the median income at its maximum value,
and what was the median income when that occurred?
(b) When was the median income at its minimum value,
and what was the median income when that occurred?
(c) The median income was declining during the 2-year
period between 2000 and 2002. Was it declining
more rapidly during the first year or the second year
of that period? Explain your reasoning.
