RECALL: $y=f(-x)$ is the reflection about the y-axis of the parent function $f(x)$. A reflection about the y-axis changes the parent function's x-coordinate to its opposite sign but retains the y-value. (e.g., if $(1, 2)$ is on the graph of $f(x)$, then $(-1, 2)$ is on the graph of $f(-x)$.) This means that if $(3, 6)$ is on the graph of $y=f(x)$, then $(-3, 6)$ is on the graph of $y=f(-x)$. The answer is Option (d).
