Today's Learning Goal:
Surface the difference between a discrete and continuous model for a given context.
Introduce continuous exponential functions.
Recognize that arithmetic sequences are linear functions by examining the constant rate of change.
Recognize that geometric sequences are exponential functions by examining the constant ratio of values over equal intervals.
Introduce the concept of the domain of a function defining the possible input values.

Lesson Summary:
In this lesson, we learned that the possible inputs for a function are called the domain. We found that some situations are best described using a discrete model and others are represented better with a continuous model. Arithmetic sequences are part of the linear family of functions and geometric sequences are part of the exponential family of functions.
