Rationalizing the Denominator Simplifying Square Roots That Contain Variables A function y=f(x) has critical points at all points x_0 where f^'(x_0)=0 or f(x) is not differentiable. Quadratic Equations with Imaginary Solutions Vote. Maxima/minima occur when f0(x) = 0. † x = a is a maximum if f0(a) = 0 and f00(a) < 0; † x = a is a minimum if f0(a) = 0 and f00(a) > 0; A point where f00(a) = 0 and f000(a) 6= 0 is called a point of in°ection.
