Question
Temperature readings $T$ (in $^{\circ} \mathrm{F}$ ) were recorded every two hours from midnight to 2: 00 PM in Baltimore on September 26,2007 . The time $t$ was measured in hours from midnight. $$\begin{array}{|c|c|c|c|c|c|c|c|c|}\hline t & 0 & 2 & 4 & 6 & 8 & 10 & 12 & 14 \\\hline T & 68 & 65 & 63 & 63 & 65 & 76 & 85 & 91 \\\hline\end{array}$$(a) Use the readings to sketch a rough graph of $T$ as a function of $t.$(b) Use your graph to estimate the temperature at 11: 00 AM.
Step 1
The x-axis represents the time $t$ (in hours from midnight) and the y-axis represents the temperature $T$ (in $^{\circ} \mathrm{F}$). The points to be plotted are (0,68), (2,65), (4,63), (6,63), (8,65), (10,76), (12,85), and (14,91). Show more…
