Answer-
The domain of g(x) is all real numbers.
Solution-
The given function is,
[tex]f(x)=6(0.25)^x[/tex]
The reflection across y-axis of a point (x, y) will be (-x, y)
So, the reflection of the given function across y-axis will be,
[tex]g(x)=6(0.25)^{-x}[/tex]
It is an exponential function. The domain of exponential functions is all real numbers and the range is all real numbers greater than zero.
Therefore, first option is correct.
