Derivative Sign Patterns
Clark, Jeffrey
College Mathematics Journal, v42 n5 p379-382 Nov 2011
Analysis of the patterns of signs of infinitely differentiable real functions shows that only four patterns are possible if the function is required to exhibit the pattern at all points in its domain and that domain is the set of all real numbers. On the other hand all patterns are possible if the domain is a bounded open interval.
