<u>Answer-</u>
The domain of g(x) is all real numbers.
<u>Solution-</u>
The given function is,
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,
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.
