Solving a quadratic inequality using the interval method.

The primary goal is to determine the level of mastery of the subject matter covered from September to December. This includes: Solving a quadratic inequality using the interval method

), and forgetting the domain of definition (ODZ) in rational equations. 6. Methodological Recommendations Following the diagnostic, the teacher should: intervals of monotonicity (increasing/decreasing)

Simplifying a complex algebraic expression or proving an identity. 5. Evaluation and Analysis Criteria its graph (parabola)

Solving a system of non-linear equations (e.g., a circle and a line).

Properties of functions: domain, range, zeros, intervals of monotonicity (increasing/decreasing), and intervals of constant sign. The function , its graph (parabola), and properties. Graph transformations (translations along axes). Equations and Inequalities: Quadratic inequalities and the method of intervals. Rational equations and inequalities.
