Resumen:
The purpose of this paper is to analyse how functions have been taught throughout 22 secondary school textbooks from the last 50 years. It has been adopted a temporal perspective, as the books examined were published from 1953 to 2010. Firstly, the definition of concept (situation, meaning, system of representation) used was the one proposed in the theory of conceptual fields, in order to analyse the concept of "function" taught in each book. Secondly, the books were categorized according to a focus on Sets, Analytical - Graphic or Hybrid. Finally, the meaning of function emphasized in each approach was analysed according to the representational system. The analysis showed that the meaning changed through time, as well as the difference in each representational system.
