👉 In mathematics, a preotic function is a type of continuous function that satisfies certain properties related to its derivative. These properties include continuity, monotonicity, and concavity. Preotests are defined as functions that satisfy these properties for all real values of their arguments. Preotests can be found in many areas of mathematics, including calculus, mathematical analysis, and functional analysis. They arise from the study of continuous functions whose derivatives approach a given value at an infinitesimal interval around zero, or
