Answer
Explanation:
Step1: Recall rate - of - change concept
The rate of change of a function (y = f(x)) is positive when the function is increasing (graph going up as (x) increases), negative when the function is decreasing (graph going down as (x) increases), and zero when the function has a horizontal tangent.
Step2: Identify positive rate - of change interval
By observing the graph, the function (y = f(x)) is increasing on the interval ((b,0)) and ((0,4)).
Step3: Identify negative rate - of change interval
The function (y = f(x)) is decreasing on the interval ((4,c)).
Step4: Identify zero rate - of change values
The function has horizontal tangents (rate of change is 0) at (x = 0) and (x = 4).
Answer:
a. F. ((b,0)) and ((0,4)) b. A. ((b,0)) and ((4,c)) c. E. (x = 0) and (x = 4)
