Comparing Linear Functions: Key Concepts and Applications

Miss Newman teaches how to compare linear functions presented in different forms, such as words, graphs, equations, and tables. She explains the concept of rate of change using examples of hikers and plant growth. The video emphasizes understanding and calculating rates of change, comparing different functions, and interpreting intercepts. Viewers are encouraged to practice these concepts independently.

What is one of the key steps in comparing linear functions?

• Ignoring the rate of change

• Using the same form for both functions

• Only using graphs

• Avoiding tables
