The given problem asks you to graph $f'(x)$, the derivative of the function $f(x)$, based on the graph of $f(x)$ provided.

Key steps to graph $f'(x)$:

1. Identify the critical points: The critical points occur where the slope of $f(x)$ is zero. These are at local maxima, minima, or inflection points of $f(x)$.

   • At these points, $f'(x) = 0$, so the derivative will cross the x-axis.

2. Determine where $f(x)$ is increasing or decreasing:

   • Where $f(x)$ is increasing, $f'(x)$ is positive (above the x-axis).
   • Where $f(x)$ is decreasing, $f'(x)$ is negative (below the x-axis).

3. Slope behavior:

   • Sharp changes in the slope (concavity) of $f(x)$ will influence the steepness of $f'(x)$.
   • At points where $f(x)$ transitions from concave up to concave down, the derivative $f'(x)$ will show corresponding changes.

Let's analyze the graph:

• At $x = 0$: The slope is negative and steep, so $f'(x)$ should have a negative value.
• Between $x = 0$ and $x = 2$: The graph increases until it reaches a peak at approximately $x = 2$. The slope of $f(x)$ is positive, so $f'(x)$ is positive and decreases to 0 at $x = 2$.
• At $x = 2$: The slope is zero (local maximum), so $f'(x) = 0$.
• Between $x = 2$ and $x = 4$: The graph decreases until it reaches a local minimum. The slope of $f(x)$ is negative, so $f'(x)$ is negative and reaches 0 at $x = 4$.
• At $x = 4$: The slope is zero (local minimum), so $f'(x) = 0$.
• Between $x = 4$ and $x = 6$: The graph increases again, so $f'(x)$ is positive.
• Beyond $x = 6$: The slope appears to flatten out, indicating that $f'(x)$ should approach a constant positive value.

Final Graph of $f'(x)$:

• Plot the values at the critical points.
• Sketch the curve, ensuring it crosses the x-axis at points where $f(x)$ has a local maximum or minimum.
• Adjust the steepness of $f'(x)$ based on how steep or flat the original function $f(x)$ is at different points.

Would you like further assistance with sketching the graph, or do you have any questions?

Here are 5 related questions that expand on this concept:

1. What are the critical points of a function, and how do they relate to the derivative?
2. How do the concavity and inflection points of a function affect its derivative?
3. Can a function have a derivative that is undefined at certain points? If so, why?
4. How does the derivative of a piecewise function behave at the points of transition?
5. How can you use the second derivative to understand the behavior of the original function?

Tip: Always check the sign of the slope of a function when analyzing its derivative graph.
