indicate which intervals are increasing, decreasing, or constant
indicate which intervals are increasing, decreasing, or constant
Answer
Explanation:
Step1: Recall function behavior rules
If the graph goes up from left - to - right, the function is increasing. If it goes down, it is decreasing. If it is a horizontal line, it is constant.
Step2: Analyze interval (1)
From left - to - right, the graph is going up. So, interval (1) is increasing.
Step3: Analyze interval (2)
From left - to - right, the graph is going down. So, interval (2) is decreasing.
Step4: Analyze interval (3)
From left - to - right, the graph is going up. So, interval (3) is increasing.
Step5: Analyze interval (4)
The graph is a horizontal line. So, interval (4) is constant.
Step6: Analyze interval (5)
From left - to - right, the graph is going up. So, interval (5) is increasing.
Step7: Analyze interval (6)
From left - to - right, the graph is going down. So, interval (6) is decreasing.
Answer:
Increasing intervals: (1), (3), (5); Decreasing intervals: (2), (6); Constant interval: (4)
