WebLet's find the critical points of the function. First we calculate the derivative. Now, we solve the equation f' (x)=0. This is a quadratic equation that can be solved in many different ways, but the easiest thing to do is to solve it by … WebLet’s do a problem. Find the critical points of the function r of x equals x² minus 5x plus 4 over x² plus 4. This is a rational function, so to take its derivative, I’m going to want to use the quotient rule. So I’m looking for the derivative because, remember, the critical points are points where the derivative equals 0 or is undefined.

This is because as long as the function is continuous and differentiable, the tangent line at peaks and valleys will flatten out, in that it will have a slope of 0 0. Such a point a a has various names: Stable point student housing albany nyWebCritical 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 ). Edit: Brian Scott is correct - critical points also include when the derivative is undefined, so ± 2 do count.
