Question:
The graph shows the amount of air pollution removed by trees in the Chicago urban region for each month of the year. From the graph we see, for example, that the ozone level starting in May increases up to June, and then abruptly decreases.
a. Are these curves the graphs of functions?
b. Look at the graph for particulates. Where is the function increasing? Decreasing? Constant?
c. On what intervals do all four lower graphs indicate that the corresponding functions are constant? Why do you think the functions are constant on those intervals?
