Key Concepts:
- Linear vs. Exponential Functions – A linear function has a constant rate of change, while an exponential function changes by a fixed percentage.
- Increasing vs. Decreasing Functions – A function can be increasing (values rise over time) or decreasing (values fall over time).
- Identifying Function Types in Graphs – Graphs of linear functions are straight lines, while exponential functions curve upward or downward.
Skills Covered:
- Determine whether a given function is linear or exponential.
- Identify whether an exponential function is increasing or decreasing.
- Choose the best function to model an airplane’s altitude over time.
