The graph below shows the battery life of a cell phone throughout the day:
Is the function linear or nonlinear?
Describe possible scenarios for the following intervals:
4-6 hours:
6-14 hours:
Name one interval in which the function is increasing.
Name one interval in which the function is decreasing.
At what rate does the phone charge?
Without the graph, it is not possible to accurately determine whether the function is linear or nonlinear.
Possible scenarios for the following intervals:
- 4-6 hours: During this time, the battery life may decrease slightly due to regular usage or battery drainage.
- 6-14 hours: The battery life may decrease steadily during this time, as it is being used continuously.
- It is also possible that during these intervals, the battery life remains constant if the phone is not being used or is on standby mode.
Without the graph, it is not possible to determine a specific interval in which the function is increasing or decreasing.
Without information about the specific charging time and remaining battery life, it is not possible to determine the rate at which the phone charges.
