This math topic focuses on identifying the domain of simple linear functions. Each problem presents a linear function in the form of an equation, and students are tasked with determining the appropriate set that best describes all possible values of the independent variable (x) that make the function well-defined. The options provided are generally sets of real numbers with or without additional constraints. This topic is designed to enhance students' understanding of function domains, particularly within the realm of basic linear equations.
