**Question:**

Select the correct answer.

What is the domain of \( y = \cos(x) \)?

---

**Options:**

- A. \( 2\pi \)
- B. \( (-\infty, \infty) \)
- C. \( [0, \infty) \)
- D. \( [-1, 1] \)

---

**Interactive Buttons:**

- **Next** (button)

---

**Explanation:**

In the given question, we need to determine the domain of the function \( y = \cos(x) \). The cosine function, \( \cos(x) \), is defined for all real numbers \( x \). Therefore, the domain is all real numbers, which is represented by:

- \( (-\infty, \infty) \)

---

Correct Answer: **B. \( (-\infty, \infty) \)**
