This is a zipped pair of PDF files. One file is a lesson on Compound Interest, leading up to Natural Base e. Continuous Compounding is covered, as well as algebra and basic function analysis of e^x. It is suitable for a Precalculus course or honors Algebra 2 course. The other file in the ZIP archive has all problems and graphs completed - basically a solution set for the lesson, handwritten. I can provide the MS Word versions of these files as separate products if people are interested. Lastly, THE SAMPLE FILE DOES NOT HAVE ALL CONTENT - A LOT HAS BEEN REMOVED FROM IT.
