In this lesson students use a given linear function to describe a situation 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.
- Describe a situation based on a given function.
- Write a function based on the description of a situation.
- Let’s pick apart functions
