The following graph corresponds to f"(x), the second derivative of f(x). If the graph does not appear, please reload the page. 1000 X 500 -500 -1000- Based on the above graph of the second derivative of f(x), determine the number inflection points of f(x). You may assume that f"(x) is continuous, f"(x) is defined for all x, and f"(x) = 0 only when x = -4, x = 0, and x = 4. Enter the number of inflection points of f(x): Determine the x-coordinates of the inflection points. Enter your answer as a comma-separated list of values. The order of the values does not matter. Enter DNE if f(x) does not have any inflection points.

## Educational Website Content: Understanding Graphs of Second Derivatives

### Graph Analysis

The graph displayed represents the second derivative of a function, denoted as \( f''(x) \).

#### Graph Description

- **Axes:**
  - The horizontal axis is labeled \( x \).
  - The vertical axis is labeled \( y \), with values ranging from -1000 to 1000.
  
- **Curve Behavior:**
  - The graph shows a smooth curve that intersects the \( x \)-axis at three points: \( x = -4 \), \( x = 0 \), and \( x = 4 \).
  - The curve exhibits positive and negative values, indicating intervals of concavity and convexity for the original function \( f(x) \).

### Inflection Points

An inflection point occurs where the concavity of \( f(x) \) changes, which corresponds to the points where the second derivative \( f''(x) = 0 \).

#### Exercise

1. **Determine the Number of Inflection Points:**
   - Based on the graph, identify how many times \( f''(x) \) equals zero.

2. **X-Coordinates of Inflection Points:**
   - Enter the \( x \)-coordinates as a comma-separated list where \( f''(x) \) intersects the \( x \)-axis.

### Instructions

- Enter the number of inflection points in the first box.
- Provide the \( x \)-coordinates for the points of inflection in the second box.
- If \( f(x) \) does not have any inflection points, input "DNE" (Does Not Exist).

*Note:* Ensure the graph is properly loaded if not visible. This helps in analyzing the behavior of the function for further calculus studies.
