How To Find Critical Points From Derivative Graph. $x=$ enter in increasing order, separated by commas. 6 x 2 ( 5 x − 3) ( x + 5) = 0 6 x 2 ( 5 x − 3) ( x + 5) = 0.
A critical point of a continuous function f f f is a point at which the derivative is zero or undefined. A function f(x) has a critical point at x = a if a is in the domain of f(x) and either f0(a) = 0 or f0(a) is unde ned.
And consequently, divide the interval into the smaller intervals and step 2: Another set of critical numbers can be found by setting the denominator equal to zero;
