Identifying Turning Points (Local Extrema) for a Function

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 … WebThe local extrema are found by solving the derivative of the function equal to zero. This is because at local extrema, the derivative changes sign from positive to negative (for a maximum) or negative to positive (for a minimum). So, setting the derivative equal to zero and solving for the critical points will give us the locations of the local ...
