The function which represents the reflection of provided function across the x-axis is,
[tex]g(x) = -5(0. 8)x[/tex]
The reflection of a function is flipping the original function with respect to a reference line.
The following steps used to for reflecting a the function-
The function given in the problem is,
[tex]f(x) = 5(0. 8)x[/tex]
The function has the positive sign. Therefore, this function is located in the first quadrant.Now this function is reflected across the x-axis. This will lead this function in the fourth quadrant, with negative sign.
Therefore, the function become,
[tex]g(x) = -5(0. 8)x[/tex]
Hence, the function which represents the reflection of provided function across the x-axis is,
[tex]g(x) = -5(0. 8)x[/tex]
