The condition f ( x + y) = f ( x) f ( y) only implies f ( x) = a x for all rational numbers x ∈ Q and for some a ∈ R. You can get this equality for all real numbers if you have more conditions, for example, if f is continuous in R or if f is Lebesgue-measurable. Share. Cite. answered Nov 27, 2015 at 6:17.

WebSep 30, 2024 · But this problem can be solved by simple number picking: plug in numbers. As stem says that "following functions f is f (x) = f (1-x) for all x ", so it should work for all choices of x. Now let x be 2 (note that: -1, 0, and 1 generally are not good choices for number picking), then 1 − x = 1 − 2 = − 1. how much is steve guttenberg worth

Webso. f ( x) = f ( − 1 x) = f ( − 1 x + 1) = ⋯ = f ( − 1 − 1 − 1 x + 1 + 1) = f ( x − 1), and so you can even explicitly shift to the left. One can actually construct any continued fraction and so you see that the function takes the same value on all rational values (even for only a finite number of operations for each number).

A = exp ( 1 / F ′ ( 1)). = exp ( ( ln A) ( log A ( x)). So log A ( x) = ( ln x) ⋅ ( 1 / ln A). In this case we have 1 / ln A = F ′ ( 1), that is, ln A = 1 / F ′ ( 1). For example if F ′ ( 1) = 10 the base A is e 1 / 10. It shouldn't be too hard to get your answer from this. how much is steve harvey worth today
