Description
What It Is:
A graph-based worksheet designed to help students determine whether each graph represents a function. Learners analyze nine different graphs and decide which pass the vertical line test — a key visual method for identifying functions.
Why Use It:
This worksheet reinforces understanding of functions, relations, and coordinate graphing. It’s ideal for visual learners and helps build foundational algebra skills needed for higher math courses like Algebra 1 and Pre-Algebra.
How to Use It:
• Examine each graph carefully.
• Apply the vertical line test — if any vertical line crosses the graph more than once, it is not a function.
• Write “Function” or “Not a Function” under each graph.
• Use as classwork, homework, or an assessment tool to evaluate concept mastery.
Grade Suitability:
Best for Grades 7–9.
• Grade 7: Introduction to functions and coordinate relationships.
• Grades 8–9: Review and reinforcement of function graphing concepts.
Target Users:
Perfect for middle school teachers, tutors, and students learning to visually identify functions and strengthen algebra readiness.
