Abstract
This paper deals with the concept of function, basic in Mathematical Analysis, and, in particular, in its graphical representation, putting our attention on plotting graphs of functions. Here, we present the findings of a study on graphical representations of functions found in mathematical notebooks of high school students. We encountered several deficiencies in plotting graphs, related to the concepts of function and asymptote, the use of scales in diagram axes and the characteristics of some functions. Besides, we discuss about the technical limitations and the didactic and cognitive difficulties that may promote their emergence, and, finally, we make some didactic recommendations for teachers.
