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. A function (y=f(x)) is increasing if as (x) increases, (y) also increases.
Step2: Analyze the graph for positive rate - of change
Looking at the graph, the function is increasing on the interval ((0,4)). There is no other interval where the function is increasing.
Step3: Recall rate - of - change for negative case
The rate of change of a function (y = f(x)) is negative when the function is decreasing. A function (y = f(x)) is decreasing if as (x) increases, (y) decreases.
Step4: Analyze the graph for negative rate - of change
The function is decreasing on the intervals ((b,0)) and ((4,c))
Answer:
a. D. ((0,4)) only b. A. ((b,0)) and ((4,c))
