Keyword: «function curves»

The article contains a brief presentation of theoretical information in the field of functional dependence of elementary functions. Practical methods that allow you to draw sketches of functions’ curves of different complexity levels are demonstrated here. In particular, the plotting of functions’curves containing modulus usually causes considerable difficulties for university entrants and first-year students. The purpose of this work is to give algorithm for plotting curves of functions containing moduli to which linear transformations are applied. The main attention is paid to the methods of plotting, and not to the study of certain types of functions.
