Which function represents g(x), a reflection of f(x) = 6(1/3)^x across the y-axis?

g(x)=

Step-by-step explanation:

a reflection of f(x) = 6(1/3)^x across the y-axis

Given f(x)=

When graph of f(x) reflects across y axis then f(x) becomes f(-x)

For reflection across y axis we replace x  with -x

f(x)=

f(-x)=

f(-x) is a reflection across the y axis  that is our g(x)

So g(x)=

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
