Which function represents a reflection of f(x) =3/8 (4)x across the y-axis?

The function represents a reflection of across the y-axis.

Step-by-step explanation:

The given function is

If a function reflected across the y-axis then the sign of x-coordinate is changed but the y-coordinate remain the same.

Mathematically it can be defined as

Let function g(x) represents a reflection of f(x) across the y-axis. So, the required function is

Therefore the function represents a reflection of across the y-axis.
