How to write a piecewise function from a given graph - Homework help online

The video tutorial explains how to write a piecewise function from a graph. It begins by identifying three equations from different lines on the graph, each with unique constraints. The tutorial then details how to determine these constraints and compile them into a piecewise function format. The process involves understanding the slope and intercept of each line and applying the appropriate constraints to form a complete piecewise function.
