The image presents a problem where you are asked to select the graph corresponding to the derivative of a given function.

1. The function in red looks like a smooth, concave downward curve (similar to a parabola) with a peak at the center. This is likely a second-degree polynomial (quadratic function), with a maximum point at \(x = 0\).

To determine the correct derivative graph, consider the following:

- The derivative of a function gives the slope of the tangent line at any point.
- Where the original function has a maximum (the peak of the red curve), the derivative will be zero because the slope is flat.
- On the left side of the maximum, the original function is increasing, so the derivative will be positive.
- On the right side of the maximum, the original function is decreasing, so the derivative will be negative.

### Let's analyze the options:
- **a.** This graph is a parabola opening upward, suggesting that the original function might have been a linear function (constant slope). This does not match the behavior we expect from the derivative.
- **b.** This graph has a zero at the middle point, changes from positive to negative, and has smooth transitions, which fits the idea that the slope is zero at the maximum point of the original function and positive to the left, negative to the right.
- **c.** This graph represents a straight line, which does not capture the behavior of the derivative of the given red curve.
- **d.** This graph shows a sharp vertical behavior, indicating discontinuities or drastic changes in slope, which does not fit the smooth behavior of the original red curve.

### Correct answer: **b**

Here are 5 related questions to deepen your understanding:
1. How can you find the derivative of a quadratic function analytically?
2. What does the second derivative of this function represent graphically?
3. How does the derivative behave at points of inflection?
4. What types of functions have a constant derivative?
5. Why does the derivative graph have a zero slope at the maximum?

**Tip:** When analyzing a function's graph, always look at the peaks and valleys to understand where the derivative will cross zero!

In this problem, you are asked to identify the graph of the derivative for a function that has a maximum. This covers key calculus concepts such as the behavior of derivatives at critical points and slope changes.
