Critical number finder
WebThe first major step to finding the relative extrema of a function f (x) is to find all critical points of the function f (x) on the domain -∞ < x < ∞. Critical points x = c are located where f (c) exists and either f ‘ (c) = 0 or f ‘ (c) is undefined. The steps for finding the critical points are as follows: Take the derivative of f (x ...

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. WebExample 2. Determine the absolute maximum of the function g ( x) = 3 x + 3 x over the interval, [ 1, 4], if it exists. Solution. The function g ( x) is continuous within the interval, [ 1, 4]. Let’s find the critical numbers of the function by finding g ′ ( x).
WebA number a in the domain of a given function f is called a critical number of f if f '(a) = 0 or f ' is undefined at x = a.
