Unit 5, Lesson 17
Interpreting Function Parts in Situations
Extra Support Materials for Algebra 1
These materials, when encountered before Algebra 1, Unit 5, Lesson 17, support success in that lesson.
Preparation
Lesson Narrative
In this lesson, students use a given linear function to describe a situation and then write functions to represent situations. In the associated Algebra 1 lesson students use inverses to find information about situations. This lesson supports students by drawing strong connections between the situation descriptions and the function, so that students can focus on the relationships with the inverse in the Algebra 1 lesson.
Reasoning abstractly and quantitatively (MP2) is essential for understanding the functions in terms of the situations given.
- Create and evaluate a function based on the description of a situation.
- Interpret (in writing) the rate of change and function values for a situation when given specific inputs.
