Original Prompt

create worksheets as descibed: Station B – Domain/Range + Writing Equations (A.2.A, A.2.I, A.2.C) Mixed graphs/contexts: Identify if situation is discrete vs continuous. Write domain & range as inequalities. For stronger kids (Group 3), add “write the linear equation that models this” or “write a system to match both conditions.” Provide leveled versions: Group 1: mostly graph-based, less reading. Group 2: mix of graphs and short-word problems. Group 3: longer contexts & STAAR-style ans...

This resource provides a comprehensive guide on understanding the domain and range of linear functions. It begins with an introduction to the concepts of domain and range, defining the domain as all possible 'x-values' and the range as all possible 'y-values' of a function. Through an example, it illustrates a continuous linear function with specified domain and range values. The document includes various group exercises that encourage collaborative practice, allowing students to determine if given functions are discrete or continuous and to identify their respective domains and ranges. Additionally, it offers independent practice for students to solidify their understanding, including identifying inequalities for domains and ranges. The resource concludes with reflection questions and a reference guide, providing structured learning opportunities around linear equations and notation.
