Identifying Input-Output Rules

The video tutorial teaches how to identify mathematical rules using input-output tables. It uses examples like plant growth, multiplication by eight, and a donut machine to demonstrate how to determine the rule that connects inputs to outputs. The tutorial emphasizes checking each potential rule to find the correct one, encouraging practice and application of these concepts.

What is the purpose of using input-output tables in the context of the video?

• To record the number of students in a class

• To measure the temperature changes

• To calculate the speed of a car

• To track the growth of a plant over time
