Question

The black graph is the graph of y=f(x). Choose the equation for the red graph. Please help!!

Answer 1

Answer:

B

Step-by-step explanation:

The black graph is the graph of y=f(x).

The red graph is the reflection of the black graph across the y-axis.

A. $y=f(x-1)$ determines the translation of the graph $y=f(x)$ one unit to the right.

B. $y=f\left(\dfrac{x}{-1}\right)$ determines the reflection of the graph $y=f(x)$ across the y-axis.

C. $y-1=f(x),\ y=f(x)+1$ determines the translation of the graph $y=f(x)$ one unit up.

D. $\dfrac{y}{-1}=f(x),\ y=-f(x)$ determines the reflection of the graph $y=f(x)$ across the y-axis.
