Graphing and Analyzing Polynomial Functions
Students identify zeros, multiplicities, and end behavior to sketch graphs of polynomial functions. They use technology to model data with polynomials.
About This Topic
Students identify zeros, multiplicities, and end behavior to sketch graphs of polynomial functions. They use technology to model data with polynomials.
Key Questions
- How does the degree of a polynomial affect its end behavior?
- What role does multiplicity play in the graph's x-intercepts?
- How can we model real-world data using polynomial functions?
Planning templates for Algebra II
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
