1. (Due September 1) We say that a function f(x) is scale-shift-invariant if for every λ>0, there exists a value yo for which y = f(x) implies that y' = f(x'), where y' = y + yo and x = 2 * x. Write down, in detail, the proof that if a differentiable function is scale-shift-invariant, then f(x) = A + a* ln(x) for some A and a.
