Answer: D.) [tex]g(x) = 6(3)^{-x}[/tex]
Step-by-step explanation: We are given an exponential function f(x).
g(x) is an exponential function that is being reflected across y-axis.
According to rules of transformations y=f(-x).
That is variable x is being multiplied by a negative sign.
In the given options [tex]g(x) = 6(3)^{-x}[/tex], the variable x is being multiplied by a negative sign.
Therefore, correct option is D option.
