The world is going through one of the deepest economic crises in recent times. The current and future scenarios are riddled with uncertainty that is not always taken into account in the analysis of the different economic functions of interest for the development of the business, and the reality is presented by static and almost perfect models of market behavior. The fuzzy sets theory allows to build suitable models from uncertain realities that present vagueness intrinsically. The use of fuzzy numbers makes possible to consider the aspects of an imprecise environment. Extreme and more possible situations of the different variables involved can be determined through the opinion of experts.  In this paper we present the fuzzy function concept applied to a case study involving economic functions, where the uncertainty is incorporated through the use of triangular fuzzy numbers.
