Example: y = x 3 − 6x 2 + 12x − 5. The derivative is: y' = 3x 2 − 12x + 12. The second derivative is: y'' = 6x − 12. And 6x − 12 is negative up to x = 2, positive from there onwards. So: f (x) is concave downward up to x = 2. f (x) is concave upward from x = 2 on. And the inflection point is at x = 2: Calculus Index.
