Find the domain of the function f(x) = √((5 − x)/(x + 1)).

Answer and explanation

Correct answer: (−1, 5]

The fraction under the square root must be non-negative, and x ≠ −1 because the denominator cannot be zero. A sign check at the critical points −1 and 5 shows the fraction is non-negative on (−1, 5]. The endpoint 5 is included because the fraction is zero there; −1 is excluded.
