Write inequalities from number lines
Write inequalities from number lines
What you'll learn
- Identify the critical values of a polynomial inequality by determining the real roots of the related polynomial equation with 100% accuracy on a summative assessment.
- Solve higher-degree polynomial inequalities algebraically and graphically, expressing the solution set using interval notation with at least 80% accuracy on a problem set.
- Explain the relationship between the sign of a polynomial expression and its graph, justifying how this relationship informs the solution set of the corresponding polynomial inequality in a written explanation of at least 150 words with accurate mathematical reasoning.
- Apply knowledge of polynomial inequalities to model and solve real-world problems, such as optimization problems, with at least 75% accuracy on application-based test questions.
