Step 1 :Given the function \(g(x)=\frac{f(x)}{8}=\frac{2^{z}}{8}=2^{z-3}\)
Step 2 :This is equivalent to the function \(f(x)\), but with the exponent decreased by 3
Step 3 :In terms of graph transformations, decreasing the exponent of a function corresponds to a horizontal shift to the right
Step 4 :Therefore, the correct answer is \(\boxed{\text{A horizontal translation to the right 3 units}}\)
