Single Variable Calculus, Chapter 1, 1.1, Section 1.1, Problem 20

The temperature readings T (in $^\circ$F) were recorded every two hours from midnight to 2:00 pm in Oklahoma on June 12, 2003. The time $t$ was measured in hours from midnight.

\begin{array}{|c|c|c|c|c|c|c|c|c|}
\hline\\
t & 0 & 2 & 4 & 6 & 8 & 10 & 12 & 14\\
\hline\\
T & 73 & 73 & 70 & 69 & 72 & 81 & 88 & 91 \\

a.) Sketch a rough graph of T as a function of $t$ using the given table.











b.) Estimate the temperature at 11:00 am using the graph in part(a).



By referring to the graph, the temperature at 11:00 am is $\approx 84{^\circ}F$
