See 9 Editor suggestions (c) Find any inflection points of f. (d) Evaluate f at its critical points and at the endpoints of the given interval. Identify local and global maxima and minima of f in the interval. (e) Graph f. 22. f(x) = x^3 - 3x^2 (-1 s x = 3) 24. f(x) = x^3 - 3x^2 - 9x + 15 (-5 s x s 4) 26. Find the value of x that maximizes y = 12 + 18x - 5x^2 and the corresponding value of y, by (a) Estimating the values from a graph of y. (b) Finding the values using calculus.
