WebStep 1: Finding f' (x) f ′(x) To find the relative extremum points of f f, we must use f' f ′. So we start with differentiating f f: f' (x)=\dfrac {x^2-2x} { (x-1)^2} f ′(x) = (x − 1)2x2 − 2x. [Show calculation.] Step 2: Finding all critical points and all points where f f is undefined. The … Then, divide the domain (all real numbers) by the critical numbers.

WebJul 9, 2024 · Here’s how: Take a number line and put down the critical numbers you have found: 0, –2, and 2. You divide this number line into four regions: to the left of –2, from –2 to 0, from 0 to 2, and to the right of 2. Pick a value from each region, plug it into the first derivative, and note whether your result is positive or negative.

WebStep 3: Plug any critical numbers you found in Step 2 into your original function to check that they are in the domain of the original function. For this function, the critical numbers were 0, -3 and 3. Let’s plug in 0 first and see what happens: f (x) = 02 ⁄ 02-9 = 0. Therefore, 0 is a critical number. ebay marked as shipped
