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

With fx(x, y) = 2x and fy(x, y) = − 2y, we find only one critical point, at (0, 0). We now find the maximum and minimum values that f attains along the boundary of S, that is, along the edges of the triangle.
WebNow we look at the critical points and the endpoints of the interval: On the closed interval -3 \leq x \leq 3 −3 ≤ x ≤ 3, the points (-3,9) (−3,9) and (1,-7) (1,−7) are relative minima and the points (-2,20) (−2,20) and (3,45) (3,45) are relative maxima.
