Suppose a 40 ${ } ^ { \circ } F$ container of water is placed in the freezer overnight.The next morning, it is put on the counter in a 70 ${ } ^ { \circ } F$ room and then at the end of the day heated to the boiling point.What is the range of the function?
A)From 40 ${ } ^ { \circ } F$ to 70
${ } ^ { \circ } F$ .
B)From the middle of the night until the middle of the next day.
C)From the first evening until the end of the next day.
D)From 32 degrees F to 212 degrees F.

The range of the function refers to the set of all possible output values, which in this context are temperatures. The water starts at 40°F, freezes at 32°F, is then placed in a 70°F room (but the water temperature itself doesn't reach 70°F before heating), and finally is heated to its boiling point, 212°F. Therefore, the range of temperatures the water experiences is from 32°F (freezing point) to 212°F (boiling point).
