Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Problem 4 Got It? You can also zoom out to view a larger area on the map in Problem 4. The function models the percent of the original area the map shows after zooming out x times.
Graph the function. Zoom the graphing utility to establish an appropriate viewing window.
