e. At what rate does the phone charge?
1. Please provide the function table so that we can determine if the function is increasing or decreasing.
2. Please provide the graphs so that we can label them as increasing, decreasing, or constant and describe the relationship between the x and y-values.
3.
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.
C. The distance a car travels in one hour: increasing.
4.
a. The graph is nonlinear.
b. 4-6 hours: The battery life may decrease or remain constant.
