$x$
Work Step by Step
RECALL:
The graph of the function $y=-f(x)$ involves a reflection about the x-axis of the parent function $f(x)$.
The parent function of the given function is $y=\sqrt{x}$.
The given function is in the form $y=-f(x)$.
Therefore, the given function involves a reflection about the x-axis of the parent function $y=\sqrt{x}$.
