-$$f ( x ) = \sqrt { x - 4 }$$
A) All real numbers
B) $\{ x \mid x \geq 4 \}$
C) $\{ x \mid x \geq 0 \}$
D) $\{ x \mid x \geq - 4 \}$

The domain of $f(x) = \sqrt{x - 4}$ consists of all $x$ values for which the expression under the square root, $x - 4$, is greater than or equal to 0. Solving $x - 4 \geq 0$ gives $x \geq 4$, which matches choice B.
