Keyword: «the sum of moduli»

The paper offers technique for presenting the topic " Linear combinations functions curves containing a modulus sign ". The article contains brief presentation of theoretical information in the field of functional dependence of elementary functions. The functions curves presented in the form of linear functions moduli sum or difference are analyzed in detail. The authors demonstrate practical methods that allow you to plot sketches of functions curves with different complexity levels. They give examples of typical tasks necessary for skills improving. The purpose of this work is to provide a systematic description of methods for functions with modulus curves plotting. At the same time, the main attention is paid to the methods of plotting, and not to the study of certain functions types.
