Question
**Problem Statement:**

Consider the function \( f(x,y) = \tan(2x - 2y) \) and the point \( P \left( \frac{\pi}{4}, \frac{\pi}{8} \right) \). Sketch the xy-plane showing point \( P \) and the level curve through \( P \). Indicate the directions of maximum increase, maximum decrease, and no change for \( f \).

---

**Task:**

Choose the correct graph of the level curve and point below:

- Options:
  - **A**
  - **B**
  - **C** (Correct choice marked)
  - **D**

Each graph is on a grid with the x and y axes labeled from -5 to 5. The graphs include various lines or curves and vectors labeled A, B, C, D.

**Correct Graph (Option C):**

- The graph shows point \( P \).
- A line is drawn through point \( P \) representing the level curve.
- Vectors are displayed to indicate directions in relation to the level curve.

---

**Question:**

Which vectors in the correct graph point in the direction of maximum increase?

- (Response format: Type A, B, C, or D. Use a comma to separate answers as needed.)

- **Answer Box:** [ ]

**Details from Graph (Option C):**

- The line through point \( P \) represents no change in the value of the function \( f(x,y) \).
- Vectors labeled A, B, C, D illustrate directions.
- Typically, vectors perpendicular to the level curve indicate the direction of maximum increase or maximum decrease.
