WebExample 1: Find all critical points of . Because f (x) is a polynomial function, its domain is all real numbers. hence, the critical points of f (x) are (−2,−16), (0,0), and (2,−16). Example 2: Find all critical points of f (x) = sin x + cos x on [0,2π]. The domain of f (x) is restricted to the closed interval [0,2π]. WebYou can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f" (x) = 0 OR if f" (x) is undefined. An example of the latter situation is f (x) = x^ (1/3) at x=0. Relevant links: http://depts.gpc.edu/~mcse/CourseDocs/calculus/concavity-inflectionOct12.pdf
