Continuing with the unit on exponential functions, today we spent some time working on creating functions that model real-world data.

## Today’s links

- Homework: HW 9.8 – Exponential Function Modeling
- Notes
- Lesson video 1 – a review of percent change problems from Algebra 1
- Lesson video 2 – setting up an exponential function equation to solve for the base (starring Mr. Kirk’s hand!). This video works through the second example from the notes linked above.
