F f x math
WebApr 20, 2016 · f: x ↦ y means that f is a function which takes in a value x and gives out y. f: N → N means that f is a function which takes a natural number as domain and results in a natural number as the result. Because you're wrong: the → and ↦ arrows mean different things. Also, W is not the set of positive numbers: that's R +. WebJul 19, 2024 · Jake, the answer is No! f (f (x)) means replace each x in f (x) by the entire function f (x). For example, if f (x) = x 3 + 13x + 9, then f (f (x)) = (x 3 + 13x + 9) 3 + 13 (x 3 + 13x + 9) + 9. However, f 2 (x) would mean (f (x)) 2 so, in the above example, f 2 (x) = (x 3 + 13x + 9) 2.

WebThere is no mistake, your result is correct. Your first equation f ( x) = y indicates that x must lie in the domain of f, and y in the range of f. What your final equation tells you is that f ( f − 1 ( y)) = y for numbers y which are in the range of f. If your range and your domain are the same, you can simply rename your variables to get f ... WebSep 24, 2024 · It seems this is all we can conclude about f. That is, pick. and any continuous function f2: ( − ∞, 1 a] → [1 a, a] with f2(1 a) = a. Then f(x) = {f2(x) x ≤ 1 a 1 x 1 a ≤ x ≤ a f1(x) x ≥ a is a solution to the functional equation. Indeed, we verify that f is continuous and that f(2007) = 2005.
