Answer:
The units of the average growth rate is number of accidents per day.
Step-by-step explanation:
We are given the following in the question:
The independent variable is the day of the year.
The function is the cumulative number of accidents since the first of the year at a certain dangerous intersection.
Average growth represents the rate at which the dependent variable changes as the independent variable changes.
Independent variable: day of the year
Dependent variable: cumulative number of accidents
Thus, the growth rate will have units
Thus, the units of the average growth rate is number of accidents per day.
