(a) Plot a line graph of these data. Let this graph be function R.
(b) Evaluate R(2009) and interpret the result. Do small or large values indicate a strong housing market?
(c) Is R continuous on its domain?
(d) Identify where R is increasing, decreasing, or constant.
(e) Write a piecewise-defined formula for R.
