Transcribed Image Text:### Finding Local Extrema of a Function
#### Problem Statement:
Find the location and value of each local extremum for the function depicted in the graph.
#### Graph Description:
The graph illustrates a function with the following characteristics:
- The x-axis ranges from -3 to 3.
- The y-axis ranges from -4 to 4.
#### Observations of the Graph:
1. **Local Maximum:**
- There is a local maximum at approximately \( x = -1.5 \). The value of the function at this point is about \( y = 2 \).
2. **Local Minimum:**
- There are two local minima. One occurs at about \( x = -3 \) and the other at about \( x = 1 \). The y-values for these points are approximately \( y = -3 \) and \( y = 0 \) respectively.
#### Detailed Points of Interest:
- **Local Maximum:**
- Location: \( x \approx -1.5 \)
- Value: \( y \approx 2 \)
- **First Local Minimum:**
- Location: \( x \approx -3 \)
- Value: \( y \approx -3 \)
- **Second Local Minimum:**
- Location: \( x \approx 1 \)
- Value: \( y \approx 0 \)
These points are crucial for understanding the behavior of the function around its local extrema. By identifying these key features, one can better analyze and understand the overall shape and properties of the function.
