Big Ideas: The input and output values can be organized as ordered pairs, in a table, or as sets of the domain and a range. Determining appropriate labels and scales will be important when depicting graphs of functions. Students will synthesize their understanding of graphs (with special attention on choosing appropriate units for the quantities) with their understanding of functions in this lesson. The task challenges students to model a real-world situation with a graph. The units and scale of the graph will be determined in context. Functions will be a fundamental concept in algebra and future high school math courses. NOTE: Function notation is addressed in later lessons. Vocabulary: relation, function, independent, dependent, ordered pair, domain, range, inequality Special Materials: Graph paper
