find out witch one is f(x), f'(x) and g(x)

The image provided shows three different curves, each in a distinct color: red, blue, and green. We are tasked with identifying which curve corresponds to \( f(x) \), \( f'(x) \), and \( g(x) \).

Here's how we can approach this:

1. **Derivative Analysis**:
   - The function \( f'(x) \) is the derivative of \( f(x) \), which means that \( f'(x) \) should indicate the slope of \( f(x) \) at each point.
   - When \( f(x) \) has a maximum or minimum (where the slope is 0), \( f'(x) \) should cross the x-axis.
   
2. **Identifying the curves**:
   - **Blue curve**: The blue curve appears to have a smooth shape with a peak and a trough, indicating a likely candidate for \( f(x) \). This function is continuous, and at its peaks and troughs, the slope should be zero. So \( f'(x) \) must cross the x-axis at these points.
   - **Red curve**: This curve crosses the x-axis at the points where the blue curve has peaks or troughs, indicating that it could be the derivative \( f'(x) \). The red curve also changes sign (positive to negative and vice versa) where the blue curve has extreme values, which further supports this idea.
   - **Green curve**: The green curve looks different in structure and does not seem to correlate with the behavior of the blue curve's slope. This indicates that it is likely the third function \( g(x) \), independent of \( f(x) \) and \( f'(x) \).

### Conclusion:
- The **blue curve** represents \( f(x) \),
- The **red curve** represents \( f'(x) \),
- The **green curve** represents \( g(x) \).

Would you like further details on how derivatives work, or any other aspect of this? Let me know if you have any questions.

Here are 5 related questions:
1. How can we determine the points of inflection of \( f(x) \) using \( f'(x) \)?
2. What is the relationship between the concavity of \( f(x) \) and the sign of \( f'(x) \)?
3. How do you graphically identify critical points (maxima, minima) on \( f(x) \) using \( f'(x) \)?
4. Can we predict the behavior of \( f(x) \) near its critical points just by looking at \( f'(x) \)?
5. What properties distinguish a function from its derivative graphically?

**Tip**: Always check where the derivative crosses the x-axis, as these points often correspond to critical points (peaks or troughs) in the original function.
