Exponential models (new A level maths)

This resource is designed to help students understand the key properties of exponential models and to give them lots of practice of examination-style questions on the topic.

It begins by recalling the key properties of exponential graphs and introduces the form of the equation used in most exponential models.

The first section contains examples designed to help students realise that the same proportional change happens over equal time periods. There are a few examples that establish this property and then an exercise of questions for students to attempt.

The main section focuses on using exponential models and begins with 2 pages of example questions chosen to show students the typical style and demands of examination questions on this topic. There is then a 17-page exercise with almost 70 questions for students to attempt themselves. The exercise includes questions where students are required to explain the significance of parameters in models, the limitations of models, and to suggest possible improvements.

Answers to the exercises are included.

Here is an example of one of my A level resources that is freely available:
