Identifying the Domain and Range of Functions in Real-World Applications

This lesson teaches how to identify the domain and range of functions by examining their applications. It explains the difference between functions and relations, using a T chart to illustrate domain and range variables. A real-world example involving cricket chirps predicting temperature is provided, with an equation to demonstrate the relationship. The lesson also covers graphing functions and discusses restrictions on domain and range, emphasizing that these restrictions depend on the specific situation. The lesson concludes by summarizing the key points about domain and range.
