The image shows the graph of the derivative function \( f' \), and you are asked to sketch the graph of the original function \( f \) based on this information.

### Key Insights for Sketching \( f \) from \( f' \):
1. **Where \( f' = 0 \):** The points where the graph of \( f' \) crosses the x-axis correspond to critical points of \( f \) (local maxima, minima, or points of inflection). In this graph, \( f' = 0 \) at \( x = -2 \).
   
2. **Where \( f' > 0 \) (Positive slope):** When \( f' \) is positive (above the x-axis), \( f \) is increasing. The graph shows that \( f' > 0 \) for \( x < -2 \), so \( f \) increases on this interval.

3. **Where \( f' < 0 \) (Negative slope):** When \( f' \) is negative (below the x-axis), \( f \) is decreasing. The graph shows that \( f' < 0 \) for \( x > -2 \), so \( f \) decreases on this interval.

4. **Slope of \( f' \):** The slope of \( f' \) provides insights into the concavity of \( f \). If \( f' \) is decreasing, \( f \) is concave down, and if \( f' \) is increasing, \( f \) is concave up.

### Steps to Sketch the Graph of \( f \):

- For \( x < -2 \), \( f' > 0 \), so \( f \) is increasing. As \( f' \) decreases in this region, \( f \) is concave down.
  
- At \( x = -2 \), \( f' = 0 \), so there is a local maximum at this point.

- For \( x > -2 \), \( f' < 0 \), so \( f \) is decreasing. Since \( f' \) continues to decrease, \( f \) is concave down in this region as well.

Therefore, the function \( f \) will have a maximum at \( x = -2 \), and it will increase to the left of this point and decrease to the right of it.

Would you like further clarifications or details? Here are some related questions for deeper exploration:

1. How does the behavior of the derivative affect the concavity of the original function?
2. What is the significance of the slope of the tangent line in the graph of \( f' \)?
3. How would the graph of \( f \) look if the slope of \( f' \) changed sign at multiple points?
4. How do inflection points of \( f \) relate to changes in the slope of \( f' \)?
5. Can the graph of \( f \) have horizontal asymptotes if the derivative approaches 0 at extreme values of \( x \)?

**Tip:** Understanding how the sign of the derivative affects the behavior of the original function is key to mastering calculus-related graphing problems.
