3. Decide if each scenario is increasing, decreasing, or constant.
A. The battery life of a
computer that is plugged in.
B. The amount of food supply
a restaurant has over the course of one day
C. The distance a car travels in one hour
4. The graph below shows the battery life of a cell phone throughout the day:
a. Is the function linear or nonlinear?
b. Describe possible scenarios for the following intervals:
4-6 hours:
6-14 hours:
c. Name one interval in which the function is increasing.
d. Name one interval in which the function is decreasing.
e. At what rate does the phone charge?
A. The battery life of a computer that is plugged in: constant
B. The amount of food supply a restaurant has over the course of one day: decreasing (assuming they serve food and it gets consumed)
C. The distance a car travels in one hour: increasing (assuming the car is moving and not stationary)
4. a. The function is nonlinear
b.
4-6 hours: The battery life of the cell phone may decrease slightly or remain constant
6-14 hours: The battery life of the cell phone may decrease gradually or rapidly
c. The function is increasing in the interval 0-4 hours.
d. The function is decreasing in the interval 14-24 hours.
e. The rate at which the phone charges cannot be determined from the given graph.
