Weband asked to find the intervals over which the original function is increasing. The question states that the original function is undefined at x = 4. According to the definition, x = 4 should not be a critical point because it's undefined in both the derivative and the original function. However, it is a point of interest as f'(x) > 0 only when ... WebCritical points are not where the function is $0.$ You want to find the points where the derivative is $0.$ Unfortunately, your function does not happen to be differentiable at $2$ or $-2,$ so you should only get one critical point (at $0$).

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 undefined at c ... WebFeb 22, 2024 · Example. Alright, let’s work through a problem together. Use Newton’s Method, correct to eight decimal places, to approximate 1000 7. First, we must do a bit of sleuthing and recognize that 1000 7 is the solution to x 7 = 1000 or x 7 − 1000 = 0. Therefore, our function for which we will use is f ( x) = x 7 − 1000. cloak\\u0027s 0z
