## Introduction

Workshop 7 focused on functions. Time was spent making connections between compound interest, geometric sequences, exponential functions and logarithmic functions. As part of this process a lesson on introducing e to students was modeled. Shifting and scaling of quadratic functions was also addressed. If you missed workshop 7 or want to go back over some of the activities done on the day, you’ll find videos of the full workshop and all the resources used or references during the workshop below.
