Answer 1

To determine which statements about the extrema of the graphed function are true, let's analyze the provided extrema:

1. **Extrema Points:**
- \( (-4, 3) \)
- \( (-2, -2) \)
- \( (0, 2) \)
- \( (2, -3) \)
- \( (4, 4) \)

2. **Behavior of the Function:**
- The function approaches negative infinity on both ends.

### Analysis of Statements:

1. **Statement: \( (-2, -2) \) is a local minimum.**
- At \( (-2, -2) \), the function value is lower than the values at nearby extrema \( (-4, 3) \) and \( (0, 2) \). **True.**

2. **Statement: \( (-5, 0) \) is a local minimum.**
- Since \( (-5, 0) \) is not one of the indicated extrema points, we cannot determine its status as a minimum based on the given information about extrema. **False.**

3. **Statement: \( (4, 4) \) is the global maximum.**
- This point has the highest function value compared to the other extrema (as \( (2, -3) \) is lower and approaches negative infinity at both ends). **True.**

4. **Statement: \( (2, -3) \) is the global minimum.**
- While it is the lowest value among the listed extrema, the function approaches negative infinity as \( x \) moves towards the ends, meaning the function has no global minimum in the sense of a highest-lowest value, which would be \( -\infty \). **False.**

### Conclusion:

The true statements are:
- \( (-2, -2) \) is a local minimum.
- \( (4, 4) \) is the global maximum.
