Algebra II with Mrs. Wieseler

January 31, 2014

   In Algebra II these past few weeks the students have been covering a topic that illustrates the concepts of growth or decay in applied real world situations.  Different phenomena can be modeled by functions that describe how things grow or decay as time passes.  Examples of such phenomena include the studies of populations, bacteria, the AIDS virus, radioactive substances, electricity, temperatures and credit payments, just to mention a few.  Any quantity that grows or decays by a fixed percent at regular intervals is said to possess exponential growth or exponential decay.  The Algebra II students are learning that as a quantity grows by a fixed percent at regular intervals, the pattern can be represented by the functions.  This is a great concept that many of them will take into their future education and careers.
