Web13. Let'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. To find out where the real values of the derivative do not exist, I look for ...

WebDec 21, 2024 · This leads us to a method for finding when functions are increasing and decreasing. THeorem 3.3.1: Test For Increasing/Decreasing Functions. Let f be a continuous function on [a, b] and differentiable on (a, b). If f ′ (c) > 0 for all c in (a, b), then f is increasing on [a, b]. WebGiven a function f, and knowing that f is defined at a point c, how do you know if c is a critical number or not? The derivative of f is equal to zero at c. The derivative of f is … red cross ethical framework
