Exploring Function Tables in Pre-Algebra

The video tutorial covers function tables, explaining how to organize input and output values using function rules. It includes examples of creating function tables and solving word problems, such as calculating the number of peanuts needed for peanut butter production and taxi service charges. The tutorial also explains graphing linear functions using the BMW method, focusing on slope and y-intercept.

What is the purpose of a function table?

• To organize the input and output of a function

• To calculate the perimeter of a rectangle

• To solve quadratic equations

• To find the area of a triangle
