D)g(x) = 3^−x
Step-by-step explanationgiven the function
it has a transformatio functio g(x), by checking the graph we can conclude the transformation was a reflection across y-xis
so, we need to apply the rule for that kind of transformation
the rule to reflect a function across the y-axis is
(x,y)→(−x,y)
therfore, we need to negate the x coordiante, hence
therefore, the answer is
D)g(x) = 3^−x
I hope this helps you
