C)neither

Question

Quizplus · Accepted Answer

The function $f(x) = \sqrt{x}$ is neither even nor odd because it does not satisfy the conditions for either. For a function to be even, $f(x) = f(-x)$ must hold, which is not true for $\sqrt{x}$ since $\sqrt{-x}$ is not defined for real numbers when $x > 0$. For a function to be odd, $f(-x) = -f(x)$ must hold, which is also not true for $\sqrt{x}$. Therefore, the function is neither even nor odd.
