Solving problems with parameters using functions graphs

The book is addressed to students and teachers, as well as applicants. It is dedicated to the tasks with parameters that are solved using the functions. The ability to build graphs can significantly facilitate the solution of many in appearance of complex tasks with parameters. The textbook is written so that the reader can independently learn to solve problems with parameters and successfully prepare for the exam. The authors focused on the types of tasks and the level of complexity B18 from the exam.
In each section, the methods for constructing the schedules of functions from the simplest to very complex are first considered. In some cases, the study of the function by elementary means is supplemented by a study using a derivative. Then the solution of problems with the parameters is dismantled in the process of which the graphs of these functions are used. For each section, tasks are given for independent solutions with answers.
The teacher will be able to use the materials of the book in the lessons when studying this section, as well as in the preparation of students for exams.
