Information
Description
What It Is:
A calculus and algebra-based worksheet focused on finding critical points, discontinuities, and intervals of increase or decrease for polynomial functions. Students practice differentiation and function analysis to deepen understanding of function behavior.
Why Use It:
Builds student fluency in identifying where functions change direction, determining maxima and minima, and understanding how derivatives reveal growth and decline. Strengthens analytical skills essential for calculus readiness.
How to Use It:
• Differentiate each function to find critical points where y′ = 0 or is undefined.
• Use the first derivative test to determine where the function increases or decreases.
• Analyze continuity and behavior at turning points.
• Apply as classwork, homework, or pre-calculus review for function analysis.
Grade Suitability:
Best for Grades 11–12.
• Grade 11: Reinforces advanced algebraic differentiation and curve sketching.
• Grade 12: Prepares for calculus-level analysis and understanding of rate changes.
Target Users:
Ideal for Algebra II, Precalculus, or Calculus teachers who want students to practice analyzing polynomial functions for critical points, turning points, and intervals of change.
