-$$y = \sqrt { 7 + x }$$
A) $[ - 7 , \infty )$
B) $( - \infty , \infty )$
C) $( - \infty , - 7 ]$
D) $[ 0 , \infty )$

Quizplus · Accepted Answer

The domain of the function $y = \sqrt{7 + x}$ consists of all $x$ values for which $7 + x$ is greater than or equal to 0, because the square root function is defined only for non-negative numbers. Solving $7 + x \geq 0$ for $x$ gives $x \geq -7$, which corresponds to the interval $[-7, \infty)$.
