how to find maximum and minimum values
Find maximum and minimum values of a function over a closed interval. Facts: Let f(x) be a function on [a,b] and c is a point in the interval [a,b]. (1) If for any point x in [a,b], f(x) â¥ f(c) (respectively, f(x) â¤ f(c)), then f(c) is the. absolute (or global) minimum value (respectively, absolute (or global) local max-. imum value) of f(x) on [a,b].
