This module builds an intuitive understanding of functions.
Students develop mathematical models for real-world situations using functions.
The activities require students to collect data, make predictions, analyze data, discuss findings, and write explanations. A primary goal of the module is to engage all students in learning the material through viewing, reading, thinking, discussing, computing, interpreting, writing, and reflecting. This enables students to construct their own knowledge of functions as they work through the activities. Students develop an intuitive understanding of function using mapping and are introduced to the vocabulary used with functions. Lesson 2 Four Representations of a Function Students use the rule of four to describe functions and to determine whether the relationship given is a function.
