Rules of Stationary Points
edit- If and , then c is a local maximum point of f(x). The graph of f(x) will be concave down on the interval.
- If and , then c is a local minimum point of f(x). The graph of f(x) will be concave up on the interval.
- If and and , then c is a local inflection point of f(x).
