# Alg2 = Algebra II

This is a required course, designed for students who are planning to attend college or pursue a technical post-secondary career.

The course emphasizes facility with symbolic expressions and forms, alongside graphical and tabular representations. It moves beyond the linear and quadratic forms learned in Algebra 1, to several other families of functions that extend those fundamental concepts. It also builds upon concepts of scaling and transformation from Geometry. Students will study polynomial, rational, exponential, logarithmic, trigonometric, and discrete families; and will build functions by combination and composition, investigating both their abstract properties and the use of functions as tools for modeling real-world situations. The course concludes with several topics from probability and statistics, with an emphasis on conditional probability and random processes.

Students taking this course are required to have a graphing calculator; and must also have access to a computer outside school, either at home or the library.

The last day to retest or submit Q3 make-up work is one week before the end of the quarter: Friday, March 9.

## Activities, exercises & other assignments

Late work will be penalized up to 5% for each scheduled day that it is overdue. The formula used is:

$adjusted\;score = {0.95^{days\;late}} \times original\;score$

Extra-credit opportunities may be announced in class from time-to-time. In many cases you will also find these posted here, or noted in the slides from that day's class. Look at each one and consider whether you want to give it a try.

Make-up work for a day’s absence is due the day following your return to class. If you complete it and turn it in on the first day you return to class, you will receive a 5% scoring bonus. Like other work, it will be penalized up to 5% for each scheduled day that it is overdue thereafter, using the formula above.

Oh, and here is a previous version of this page from the first quarter and another from the second quarter for your reference.
