Linear Functions Worksheet | Function Notation & Vertical Line Test | Algebra 1
Give Algebra 1 students complete, structured practice with linear functions — from identifying functions to mastering function notation. Students determine whether relations are linear functions using mappings, tables, and ordered pairs, then apply the vertical line test to graphs. From there, they work through function notation f(x): evaluating linear functions with numeric inputs, solving for x given an output, and tackling expression inputs like f(x+1) and f(2x). With 60+ problems and full an
