Concept explainers
Thermic Effect of Food The metabolic rate of a person who has just eaten a meal tends to go up and then, after some time has passed, return to a resting metabolic rate. This phenomenon is known as the thermic effect of food. Researchers have indicated that the thermic effect of food. Researchers have indicated that the thermic effect of food (in kJ/hr) for a particular person is
where
a. Graph the function on
b. Find the average rate of change of the thermic effect of food during the first hour after eating.
c. Use a graphing calculator to find the instantaneous rate of change of the thermic effect of food exactly one hour after eating.
d. Use a graphing calculator to estimate when the function stops increasing and begins to decrease.
