Graphing Functions with Input-Output Tables

The video tutorial explains how to use input-output tables to graph a function. It begins by introducing the concept of input-output tables and how they relate to graphing functions. The teacher demonstrates how to calculate output values using a function rule, specifically Y = 2X + 2, by substituting input values. The tutorial then shows how to use these calculated values to plot points on a graph, connecting them to form a line that represents the function. The video emphasizes the importance of understanding the order of operations and provides a visual guide to plotting points on a graph.
