The temperature of a chemical reaction oscillates between a low of
and a high of . The
temperature is at its lowest point at time , and reaches
its maximum point over a two and a half hour period. It then takes the same
amount of time to return back to its initial temperature. Let
denote the temperature of the reaction hours
after the reaction begins.

Include units in your answer.

(b) What is the midline of the function ?
Include units in your answer.

(c) What is the amplitude of the function ?
Include units in your answer.

(d) Based on your answers above, make a graph of the function
on a piece of paper.
