Understanding Linear Functions and Rates

The video covers linear functions, proportional relationships, and graphing. It discusses graph ordering, explores proportional relationships through examples like Jada's earnings and converting feet to yards, and compares savings rates between Noah and Elena. The lesson concludes with a summary and homework on graph analysis and linear equations.

What is the main topic discussed in the introduction of the lesson?

• Polynomial functions

• Exponential functions

• Linear functions

• Quadratic functions
