The graph of f(x) = 6(0.25)x and its reflection across the y-axis, g(x), are shown.

what is the domain of g(x)?

all real numbers
all real numbers less than 0
all real numbers greater than 0
all real numbers greater than or equal to 0

I will assume that function f(x) = 6(0.25)^x

The domain of this function is all the real numbers.

Reflection accross the y-axis => the argument is multiplied by - 1. and g(x) is 6(0.25)^(-x).

The graph of the original function flips around the y-axis, but the domain keeps being all the real numbers.

all real numbers
