Introduction to Functions Guided Notes

Introduce students to functions with these no-prep guided notes! Students learn what a function is, identify whether a relation is a function, explore multiple function representations, and use the Vertical Line Test to determine whether a graph represents a function. Guided examples and practice activities help students build a strong foundation before moving into linear functions and function notation.

This resource includes:

Guided notes with fill-in-the-blank vocabulary
Practice identifying functions
Multiple function representations, including:
Ordered pairs
Tables
Mapping diagrams
Graphs
Domain and range
Vertical Line Test
Guided graphing practice
Answer key

Students will learn how to:

Define a function and a relation
Identify domain and range
Determine whether a relation is a function
Recognize functions from tables, graphs, mapping diagrams, and ordered pairs
Use the Vertical Line Test
Graph linear functions from an equation

This resource is ideal for 8th Grade Math, Pre-Algebra, and Algebra 1 and works well for guided instruction, interactive notebooks, intervention, review, or independent study.

Topics: Functions, identifying functions, function representations, domain and range, vertical line test, mapping diagrams, ordered pairs, graphing functions, guided notes, Algebra 1, Pre-Algebra.
