WebApr 1, 2015 · I use the definition: a critical point for a function, f is a point (number, value), c in the domain of f at which either f'(c)=0 or f'(c) does not exist. f(x) = x-3lnx f'(x)=1-3/x=(x-3)/x For this function, f'(x) does not exist for x=0, but the domain of f is (0,oo), so 0 is not a critical point for f. f'(x)=0 at x=3 which is in the domain of f, so 3 is a critical number for f. … WebNov 19, 2024 · Definition We say that x = c x = c is a critical point of the function f (x) f ( x) if f (c) f ( c) exists and if either of the following are true. f ′(c) =0 OR f ′(c) doesn't exist f ′ ( c) …

WebLet's say we'd like to find the critical points of the function f ( x) = x − x 2. Finding out where the derivative is 0 is straightforward with Reduce: f [x_] := Sqrt [x - x^2] f' [x] == 0 Reduce [%] which yields: (1 - 2 x)/ (2 Sqrt [x - x^2]) == 0 x == 1/2 how do i redownload minecraft windows 10
