reSolve: Real-World Algebra: Exponential Functions

This sequence of two lessons explores exponential functions as seen in the real world, linking the representations of function rules, graphs and tables of values. Students consider real-world objects and data that can be described using exponential functions. They use simulations and modelling to investigate transformations, reflections and stretches to graphs of exponential functions and how these are reflected in parameters in the function rules. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources. This sequence is part of the reSolve: Mathematics by Inquiry special topic 'Bringing the real world into algebra'.
