By using Desmos and Google Sheets, we will create an activity that models real-world exponential decay per standard,

 A1.27 Interpret the parameters of functions in terms of a context. Extend from linear functions, written in the form mx + b, to exponential functions, written in the form a(b)^x 

from Alabama Course of Study. 

We will model the depreciation of a car over time. 

This standard builds conceptual understanding by having students explore how each parameter in a function affects its graphical and contextual behavior.
