Step 1
However, based on typical interpretations of such graphs, we can make some educated guesses: A. Time is a function of temperature: This is typically not true. Time progresses independently of what the temperature is doing. B. Temperature is a function of time: Show more…

Temperature readings $T$ (In$^{\circ} \mathrm{F}$) were recorded every two hours from midnight to $2 : 00 \mathrm{PM}$ in Phoenix on September $10,2008$ The time $t$ was measured in hours from midnight. $$\begin{array}{|c|c|c|c|c|c|c|c|c|}\hline t & {0} & {2} & {4} & {6} & {8} & {10} & {12} & {14} \\ \hline T & {82} & {75} & {74} & {75} & {84} & {90} & {93} & {94} \\ \hline\end{array}$$ (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 $9 : 00$ AM.

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.
