The video tutorial covers input-output tables and graphing linear functions. It begins with creating an input-output table for a given function, emphasizing the importance of choosing appropriate x-values. The tutorial then presents a real-life example of a bicycle rental company, explaining how to create a cost function and graph it. Finally, it compares two companies' rental costs using linear functions, teaching students to analyze and make cost-effective decisions.

What is the initial function discussed in the lesson?

• y = 2/3x - 3

• y = 3x - 2

• y = x/3 - 2

• y = 2x - 3
