A)Non-negative real numbers x
B)All real numbers x

E)All real numbers x such that x < 4

Quizplus · Accepted Answer

The domain of $f(x) = \frac{\sqrt{x + 4}}{4 + x}$ is all real numbers x such that $x > -4$, because the square root requires $x + 4 \geq 0$, and the denominator $4 + x$ cannot be zero, which it never is under this condition.
