Answer:

The required function -  g(x)=\frac{1}{2}(3)^{-x}

Step-by-step explanation:

Given : Function represents g(x), a reflection of f(x) =\frac{1}{2}(3)^x across the y-axis

To find : Which function represents the g(x)?

Solution :

The function f(x) =\frac{1}{2}(3)^x

The function f(x) reflected across y-axis to form g(x)

The reflection of the point (x,y) across  the y-axis is the point (-x,y).

f(x,y)→f(-x,y) , the graph of f(x) is reflected across y-axis.

Let y=\frac{1}{2}(3)^x

After reflection across y-axis is

g(x)=\frac{1}{2}(3)^{-x}

The required function.

Refer the attached graph below.
