Exploring Linear Functions Through Multiple Representations

The video tutorial introduces multiple representations of linear functions, including tables, graphs, and equations. It provides examples using real-world scenarios like parking garage fees and cell phone bills. The tutorial guides students through creating tables, graphs, and equations from verbal descriptions and encourages them to apply these skills in a student exercise involving space camp costs.

What is a function in mathematical terms?

• A mathematical operation

• A type of graph

• A relationship between two variables

• A set of numbers

How are real-world situations related to linear functions in these examples?

• They are only represented by graphs

• They are represented by equations, tables, and graphs

• They are represented by the slope

• They cannot be represented by linear functions
