Step 1 :The function given is a composition of several basic functions. To find its inverse, we need to reverse the operations in the reverse order. The operations are: cubing, adding 5, taking the fifth root, and subtracting 1. The inverse operations are: adding 1, raising to the power of 5, subtracting 5, and taking the cube root.
Step 2 :The inverse function should be \(s^{-1}(x) = \left((x+1)^{5}-5\right)^{\frac{1}{3}}\)
Step 3 :\(\boxed{s^{-1}(x) = \left((x+1)^{5}-5\right)^{\frac{1}{3}}}\)
