Math Problem Statement
Solution
From the graph you have provided, we can analyze the intervals where the function is increasing, decreasing, and determine the local maximum and minimum values.
Step-by-Step Analysis:
-
Increasing Intervals: The function is increasing when the slope of the graph is positive. Observing the graph:
- The function increases from to (before reaching a local maximum).
- It also increases from onward.
Increasing Intervals:
-
Decreasing Intervals: The function is decreasing when the slope is negative. From the graph:
- The function decreases from to (after the local maximum but before the local minimum).
Decreasing Interval:
-
Local Maximum: A local maximum occurs where the function changes from increasing to decreasing. This happens at .
Local Maximum:
- The value of at appears to be around .
-
Local Minimum: A local minimum occurs where the function changes from decreasing to increasing. This happens at .
Local Minimum:
- The value of at is around .
Summary:
- Increasing Intervals: and
- Decreasing Interval:
- Local Maximum: At ,
- Local Minimum: At ,

Formulas
Increasing/Decreasing intervals: Use the derivative f'(x) > 0 for increasing, f'(x) < 0 for decreasing.
Local Maximum: Occurs where the function changes from increasing to decreasing (f'(x) = 0 and f''(x) < 0).
Local Minimum: Occurs where the function changes from decreasing to increasing (f'(x) = 0 and f''(x) > 0).
