Which of the following is the domain of the function f(x) = √(16 − x²) over the real numbers?

Answer and explanation

Correct answer: [−4, 4]

For the square root to be real, its radicand must be non-negative: 16 − x² ≥ 0. This gives x² ≤ 16, or −4 ≤ x ≤ 4. The endpoints are included because the function equals 0 at x = −4 and x = 4. Therefore, the domain is [−4, 4].
