Option-B is correct that is y=f(x/-1) determines the reflection of the graph y=f(x) across the y-axis.
Given that,
The graph in black represents the y = f(x).
We have to pick the equation for the graph in red graph.
We know that,
The black graph is the graph of y=f(x).
The black graph is reflected across the y-axis in the red graph.
A. y=(x-1) determines the translation of the graph y=f(x) one unit to the right.
B. y=f(x/-1) determines the reflection of the graph y=f(x) across the y-axis.
C. y-1=f(x) determines the translation of the graph y=f(x) one unit up.
D. y/-1=f(x) determines the reflection of the graph y=f(x) across the y-axis.
Therefore, Option-B is correct that is y=f(x/-1) determines the reflection of the graph y=f(x) across the y-axis.
