Transcribed Image Text:The image showcases a problem set involving the function \( f(x) = 2x^3 - x^2 \) and the task is to find its derivatives: \( f'(x) \), \( f''(x) \), \( f'''(x) \), and \( f^{(4)}(x) \).
### Graphs and Diagrams Explanation
There are four graphs displayed on a common screen:
1. **Graph of \( f(x) \)**:
- This is a cubic function graph. It appears to have a traditional cubic curve shape, crossing the y-axis near the origin.
- The graph has two turning points, reflecting the local maxima and minima.
2. **Graph of \( f'(x) \)**:
- The first derivative graph, typically representing the slope of \( f(x) \).
- This graph helps identify the points where \( f(x) \) has local extrema (where \( f'(x) = 0 \)).
3. **Graph of \( f''(x) \)**:
- Represents the second derivative, indicating the concavity of \( f(x) \).
- Points where \( f''(x) = 0 \) correspond to inflection points on \( f(x) \).
4. **Graph of \( f^{(3)}(x) \)**:
- Shows the third derivative, reflecting the rate of change of concavity.
- It confirms the behavior of concavity increase or decrease.
Each graph has labeled axes, with \( y \) and \( x \) values marked. The graphs demonstrate how derivatives influence and describe the behavior of the function \( f(x) \) at various points across the x-axis.
Beyond these values, the image might also show the use of horizontal grid lines to assist in sketching and visualizing precise mathematical aspects of each graph's curve.
