Question

State the phase shift for the graph.

The given task is to graph one complete cycle for the function:

\[ y = 4 - 3 \tan\left(\frac{1}{3}x + \frac{\pi}{6}\right) \]

### Description of the Graphs

The diagram consists of multiple graphs showing the transformation of a tangent function. Each subplot is trying to depict a segment of the function over a specified range.

#### Axes and Labels

- The horizontal axis (x-axis) ranges from \(-\frac{3}{4}\pi\) to \(3\pi\).
- The vertical axis (y-axis) ranges approximately from \(-30\) to \(30\).

#### Graph Details

- Each graph shows segments of a transformed tangent function.
- Asymptotes, typical for tangent functions, are evident where the function's value tends toward positive or negative infinity.
- The function appears to have vertical asymptotes where the graph is not defined.

#### Function Description

- The basic tangent function has been shifted and stretched:
  - **Vertical Shift**: The "+4" shifts the graph up by 4 units.
  - **Amplitude**: The multiplication by "−3" flips the graph vertically and stretches it.
  - **Horizontal Shift**: The argument \(\frac{1}{3}x + \frac{\pi}{6}\) involves a phase shift and stretching due to \(\frac{1}{3}\).
  - The cycle of the transformation affects the angle and the position of the vertical asymptotes.

#### Evaluation

- The correct graph accurately represents the transformed tangent function over its complete cycle, from \(-\frac{3}{4}\pi\) to \(3\pi\).
- The check mark indicates which of the depicted functions represents this transformation correctly.

### Conclusion

Understanding these transformations is critical for mastering trigonometric functions and their graphical representations. This exercise demonstrates the impact of parameter changes on the tangent function's shape and position.
