APPLICATION OF THE GRAPHICAL METHOD IN SOLVING PROBLEMS WITH A PARAMETER

Solving problems with the parameter graphic method is one of the methods that often cause certain difficulties in students that are due to the inability to build graphs of the equations or depict many solutions of inequalities and interpret the results obtained graphically in an analytical form, consider all possible cases and draw the right conclusions. The article discusses the features of the application of the graphic method of solving equations, systems of equations and inequalities with the parameter, which is given little attention to the school. Several approaches are given and the feasibility of their use in each case is justified.
