Unformatted text preview: Theorem 3.2 Relative minimums/maximums occur only at critical numbers. At relative min/maxs, the derivative is either 0 or undefined. Critical Numbers Critical Numbers Let f be defined at c. If f ’(c) = 0 or if f ‘ is undefined at c, then c is a critical number of c. Finding Extrema On a Closed Interval Finding Extrema On a Closed Interval (1) Find the critical #s of f in (a , b). (2) Evaluate f at each critical # in (a , b). (3) Evaluate f at each endpoint of [a , b]. (4) The least of these values is the minimum. The greatest is the maximum.
