Answer:
B. y=f(x/2)
Explanation:
In the graph, the vertex of the black graph, the graph of y =f(x) is:
[tex](2,2)[/tex]
The vertex of the red graph is at:
[tex](4,2)[/tex]
From the given options:
[tex]\begin{gathered} Black:f(2)=2 \\ Red:f(\frac{4}{2})=f(2)=2 \end{gathered}[/tex]
The equation of the red graph is:
[tex]y=f(\frac{x}{2})[/tex]
Option B is correct.
