Finding Global Maxima and Minima
personal.math.ubc.ca › ~CLP › CLP1Corollary 3.5.13. Let f(x) f ( x) be a function on the interval a ≤ x≤ b. a ≤ x ≤ b. Then to find the global maximum and minimum of the function: c = a c = a or c =b. c = b. That is — compute the function at all the critical points, singular points, and endpoints. Evaluate f(c) f ( c) for each c c in that list.
