Question

Draw the temperature-times graph in each of the following cases:
(i) $\begin{matrix} Time (in hours) : & 7 : 00 & 9 : 00 & 11 : 00 & 13 : 00 & 15 : 00 & 17 : 00 & 19 : 00 & 21 : 00 Temperature in (^{\circ} F) : & 100 & 101 & 104 & 102 & 100 & 99 & 100 & 98 \end{matrix}$
(ii) $\begin{matrix} Time (in hours) : & 8 : 00 & 10 : 00 & 12 : 00 & 14 : 00 & 16 : 00 & 18 : 00 & 20 : 00 Temperature in (^{\circ} F) : & 100 & 101 & 104 & 103 & 99 & 98 & 100 \end{matrix}$

Solution

(i) We represent time along x-axis and temperature (in $^{\circ} F$ ) along y-axis. Now plot the points (7:00,100), (9:00,101), (11:00, 104),(13:00,102), (15:00,100), (17:00,99), (19:00,100) and (21:00,98) on the graph and join them in order to get the required graph as shown on the graph.

(ii) We represent time along x-axis and temperature (in $^{\circ} F$ ) along y-axis. Now plot the points (8:00,100), (10:00, 101), (12:00,104), (14:00,103),(16:00,99), (18:00,98), (20:00,100) on the graph and join them in order to get required graph as shown on the graph.
