what is the relationship between f(x), f'(x) and f''(x) in finding the concavity and point of inflextion?

OpenStudy (shiraz14):

f'(x)=0 for turning (incl. convex/concave/inflexion) points. f''(x)>0 => min. turning pt. f''(x)<0 => max. turning pt. f''(x)=0 => pt. of inflexion. Solve for all these equations to find x, then sub. x into f(x) to find the coordinates of the turning point.
