Which graph is the result of reflecting f(x) = one-fourth(8)x across the y-axis and then across the x-axis?
the function g(x)=8(4x) is reflected across the x-axis to create f(x).

on a coordinate plane, 2 exponential functions are shown. function f (x) approaches y = 0 in quadrant 3 and decreases into quadrant 4. it crosses the y-axis at (0, negative 8). function g (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. it crosses the y-axis at (0, 8).

what is the equation of f(x)?

f(x)=8(4)x
f(x)=−8(4)x
f(x)=8
f(x)=−8
