  In the frame of the project EFOP-3.6.1-16-2016-00022 „Debrecen Venture Catapult Program" it was held an occasion among secondary school students the aim of which was formation of that concept which is very important in the engineering area. In many cases in order to solve problems necessary that students have an "ideal" function concept image (the image is interrelated with the notion of the concept) and they can change between different representations of the function. In our paper we will show the experiences of the occasion in which was formed the function concept by investigation of several relationships from the everyday life and engineering area with the help of individual and cooperative learning method.

  The concept of the function and the different geometrical transformations play important role in the technical sciences. Since geometric transformations are functions, so-called geometric functions, therefore, in this study, we present a possible way of that, how can we apply the animations of the geometrical transformations which are made with GeoGebra in the formation process of the function concept in the primary and secondary school level.

  The concept of function is fundamental importance to the mathematics. Since the most mathematical concept is not acquired in one step [13], thus we have to take a long journey for developing of the function concept. One of the aim of this process to develop an effective concept image which have an important role in problem solution. The students decides on the basis of a concept image whether a given mathematical object is an example or nonexample of the concept. (Vinner & Dreyfus, 1989). In this paper we are looking for the answer of the following question: what are the concept image of the function concept formed of the students by the end of the primary school (8th grade) and the first year engineering university students?
