f(x) = (8x+5)/(2x-4)

That is defined on its maximal domain. The curve y = f(x) is transformed into the curve y = g(x) by the following sequence of transformations:

Dilation by a factor of 2 from away the y-axis, then

Translation in the negative y-direction by 8 units, then

Reflection in the x-axis, then

Translation in the negative x-direction by 8 units,

Dilation by a factor of 1/2 away from the x-axis, then

Reflection in the y-axis

Determine an expression for g(x) of the form (ax+b)/(cx+b)

Determine an expression for f^-1(x).
