monday 9/16

alg II P - finish 131-132 in RFM workbook; test now thursday

alg II HP - text #2-10 evens, 11, 46 in 5-3 section of book


alg I P -  keep p. 184 #1-6 text to turn in next week

alg I review guide for test 9/19

For the test on Friday, be prepared to:


solve a multi-step equation:   3x+5-x = 25
solve an equation with variables on both sides:  3x - 8 = 7x + 16
solve and graph the same problems as above but as an inequality
isolate a variable in a 2 variable equation or formula
solve an absolute value equation:  /x+7/ - 4 = 25

Word problems:
be able to set up a proportion in a problem that compares two things - one big, one small
be able to set up an equation with variables on both sides when the problem is talking about the better of 2 options.
be able to set up an inequality when finding the better of 2 options.
be able to use the triangle sum theorem to set up a multi step equation and solve to find x.


Reminders:  remind yourself how to convert a percent into a decimal!

Friday 9/12

alg II P-  still got that test next week!  review guide is on this blog a post or two earlier.

alg II HP -  nice job finishing the first unit; we start unit II on Monday- Quadratics   If you have not turned in the POU... get it in immediately


alg I P - unit 1 test on Friday 9/19  4 things to turn in on Monday  #2-7 from textbook, pgs. 27, 36 and 37 from RFM workbook

alg II P Review Guide for Unit 1 test on Tuesday

1.  Make sure you can graph an equation based on its parent function and transformations:

ex. 1  y = -(x+2)^3 -7  is a cubic function that has 3 transformations with its major turning point at
(-2, -7)


2.  Be able to identify transformations by name.  In the example above, I would say:  vertical reflection, horizontal shift of 2 to the left, vertical shift down 7.


3.  Be able to write domain and range of a function in interval notation.

ex. 2   for the equation in ex. 1, I would say that all values can be used for x so domain would be
(-infinity, infinity).  However, the graph is a negative parabola and it cannot go higher than -7, so its range would be (-infinity, -7)  except it would be a hard bracket next to the -7 ( I can't find that symbol in this application).


4.  Be able to graph a piecewise function from an equation.

ex.  3   y= x+4 when x<3 and  y = x^2+5 when x >3



5.  Be able to go in reverse of the above.  Look at a graph of a piecewise function and be able to write the equation including the intervals for each piece.

alg II P _ finish 7 problems graphs

alg II HP - study!!!!!!!!!!!!!!!!!!!!

alg I p- finish rfm p. 37 and turn it in next Monday.

Monday 9/8

alg II P -  finish #20-31 in 5-1 text


alg II HP - no hw but it is worth your while to look at more piecewise functions #22,24,25 in 9-2 of text.  Also, you should be looking at the study guide and preparing for the test on Thursday.
