WebMay 2, 2016 · Prove that for all a, b ∈ ( 0, ∞), f ( a b) = f ( a) + f ( b). [Hint: Let g ( x) = f ( a x)] My solution : We know that. f ( x) = ∫ f ′ ( x) d x = ∫ 1 x d x = ln ( x) + C. Also, we are given that f ( 1) = 0, so f ( 1) = ln ( 1) + C = 0, which gives us C = 0. Therefore, f ( x) = ln ( x). Now, by the laws of logarithm, we have ln ( a b ...
