Find the domain of f.
-$$f ( x ) = \sqrt { x - 17 }$$
A) $\{ x \mid x \geq 0 \}$
B) $\{ x \mid x \geq 17 \}$
C) All real numbers
D) $\{ x \mid x \geq - 17 \}$

The square root function requires its argument to be non-negative, so we need to have $(x-17) \geq 0$ in order for the function to be defined. Solving for $x$, we get $x \geq 17$, which means the domain of $f$ is $\{ x \mid x \geq 17 \}$.
