### What is an exponential model?

**Exponential models** occur when a practical situation is applied to an exponential function. The following videos will show you how to graph exponential functions from real scenarios using exponential models in HSC Standard Math. It also covers how to work out **Exponential Growth **and **Decay.**

### Exponential Growth and Decay

The following video explains the concept of exponential growth and decay and goes through a worded problem.

### Example of Exponential Growth

The following video is a HSC example of exponential growth.
