#### Work Step by Step

RECALL:
The function $y=f(-x)$ involves a reflection about the $y$-axis of the parent function $f(x)$.
The parent function of the given function is $y=\sqrt[4]{x}$.
The graph of the given function involves a reflection about the y-axis of the parent function $y=\sqrt[4]{x}$.
Thus, to graph the given function:
(1) Graph the parent function $y=\sqrt[4]{x}$ .
(Refer to the red graph in the attached image below)
(2) Reflect the parent function's graph about the y-axis. This can be done by changing each x-coordinate of the points of the parent function to its opposite sign while keeping the value of the y-coordinate of each point.a
