Which function represents g(x), a reflection of f(x) = 6across the y-axis?
2 answers:
Answer: D.)
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 , the variable x is being multiplied by a negative sign.
Therefore, correct option is D option.
