WebAug 19, 2024 · Correct. Answer: E. OR, as f (a+b)= f (a)+f (b) must be true for all positive numbers a and b, then you can randomly pick particular values of a and b and check for them: For example: a = 2 and b = 3. A. f ( a + b) = f ( 5) = 5 2 = 25 ≠ f ( a) + f ( b) = f ( 2) + f ( 3) = 2 2 + 3 2 = 13. Web然而F(c)=f(c)- [f(1)-f(0)]c-f(0)却一时半会判断不出来是否为0。这个时候就有同学开始着急了,觉得是自己想错方向了。别急,也别放弃。因为显然题目中的已知条件你还没用完啊。点C在直线AB上,这个条件你还没用呢!!又这个条件可得[f(1)-f(0)]c=f(c)-f(0)。 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 ... openssl list -cipher-algorithms
