**P****recalculus** is currently developing an understanding of exponential functions (and their inverses, logarithms) in a variety of ways over the next few weeks. We are opening our investigation of exponentials via an exploration of inverse functions using a SpringBoard investigation called "Code Breakers." We will move from this more numerical and algebraic look at the concept of inverses to the graphs of exponential and logarithmic functions. The first homework on this topic, due February 6th, will be purely dedicated to honing the graph of exponential functions. We will progress through the exponentials using investigations and formative assessments from the work of

Mathematics Assessment Project,

Dan Meyer, and College Board's

Springboard materials. Please find reference sheets, review packets, and presentations in the embedded folder below:
