2. Chicago's average monthly rainfall, $R = f(t)$ inches, is given as a function of
month, $t$, in the table below (January is $t = 1$) Solve and interpret the following:
Chicago's average monthly rainfall
\begin{tabular}{|c|c|c|c|c|c|c|c|c|}
\hline
t & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\
\hline
R & 1.8 & 1.8 & 2.7 & 3.1 & 3.5 & 3.7 & 3.5 & 3.4 \\
\hline
\end{tabular}
(a) $f(t) = 3.7$
(b) $f(7) = $
(c) Does the fact that $f(5) = f(7)$ violate the definition of a function?
