What is the domain of the function \(f(x)=\sqrt{\frac{x+3}{5-x}}\)?

Answer and explanation

Correct answer: \([-3,5)\)

For a real square root, the radicand must be non-negative, and its denominator must be nonzero. The critical points are \(-3\), where the numerator is zero, and \(5\), where the denominator is zero. Sign analysis gives \(\frac{x+3}{5-x}\ge 0\) for \(-3\le x<5\). Thus \(-3\) is included, but \(5\) is excluded, so the domain is \([-3,5)\).
