**Using the Graphing Utility to Graph \( f(x) = 2 \sin(x) + x \)**

This image displays a graph created with Desmos, an online graphing utility, to visualize the function \( f(x) = 2 \sin(x) + x \).

### Graph Explanation

- **Function**: The graph represents \( f(x) = 2 \sin(x) + x \). 
- **Axes**: The horizontal axis is labeled as \( x \), and the vertical axis is labeled as \( y \).
- **Graph Features**:
  - The curve demonstrates an oscillating sine function with an additional linear component \( x \), causing a phase shift and change in amplitude compared to the standard sine wave.
  - There are two labeled points on the graph:
    - \( (-\frac{4\pi}{3}, -2.457) \)
    - \( (-\frac{2\pi}{3}, -3.826) \)

The graph visually illustrates how the linear term \( x \) affects the sine wave, resulting in a transformed wave pattern. The labeled points help pinpoint specific coordinates for analysis.

**Graph Description:**

The graph displayed on the left depicts a section of a trigonometric function, likely sinusoidal, with a focus on the interval \([-2\pi, 0]\). The x-axis represents the interval in question, with important intercepts at approximately \(-2\pi\) and 0. The y-axis shows vertical values ranging from around -10 to 5, suggesting significant oscillation within this range.

**Instruction:**

Identify the locations of transition points on the interval \([-2\pi, 0]\).

(Give your answer in the form of a comma-separated list. Express numbers in exact form. Use \(\pi\) where needed.)

**Student Response:**

\( f \) has transition points at \( x = \frac{4\pi}{3}, \frac{2\pi}{3}, 0 \).

**Feedback:**

Incorrect
