Developing Function Rules from Tables and Real-World Situations

This lesson focuses on writing function rules based on given tables and real-world scenarios such as profit calculations in advertising and sales. Students will learn to identify independent and dependent variables to create mathematical expressions that model relationships. For example, they will develop a function rule for a journalism class earning $25 per page of advertising and for a choir selling audio tapes related to their production costs. The goal is to effectively translate real-world situations into mathematical functions, enhancing problem-solving skills.
