Abstract

The article is devoted to binary relations. Graphs of relations of the type |y| = f(x) are studied, where y = f(x) is a certain elementary function. Attention is also paid to the use of graphs of relations when solving systems of two equations with two unknowns in the field of real numbers. At the end, several tasks are given to practice the presented ideas.
