Tuesday 10/24

alg II hp -  Travolta vs. Stallone!  First day of end behavior of polynomials.  We also did #50 on
 p. 195.  Hw is p. 162 #11, 13, 17, 19, 21.


alg II -  reviewed the perf task and test.  Did #50 on p. 195.  Factor practice.  Hw is the 5 factor problems that were on the board.


alg I -  unit test day.  Last day of the graphing unit.

Monday 10/ 23

alg II hp -  We reviewed our unit test from Friday and took our pre-test of the new unit.  Hw is to factor the 5 polynomials that I put on the board.


alg II -  We took our unit test today.  If you missed it, you will make it up tomorrow or when you return.  No hw.


alg I -   We prepared for tomorrow's test on graphing.  We had a line of best fit problem and we graphed many equations using the whiteboards.   Hw is to study using the review guide.

Review Guide for algebra I periods 4-6

There are 10 problems on the unit test on graphing

3- graphing situations

3 - graphing equations

4 - making a scatterplot, finding the equation for a line of best fit, making predictions


Here are some sample problems

1.   graph:  y = -4x + 5
2.  graph:  8x - 2y = 15
3.  graph: y = x^2 - 3x - 7
4.  create a graph for revenue vs. sandwich sales where each sandwich costs $4.50
5.  create a graph for distance vs. time for a runner going up a mountain and then down it.
6.  create a graph for the Pico bus going from Westwood to SM and making 10 stops.
7.  For the scatterplot, go to p. 257 in the book and do #3, 4.

Friday 10/20

alg II hp -- First unit test!  Well done.   New seats on Monday.



alg II -   Performance task on quadratics.  Unit test on Monday.


alg I - More review for our test on Tuesday.  No hw but get ready for the test.  Check out the review guide on another post.

Thursday 10/ 19

alg II hp -  Looks like we had an application on determining if a quad function can produce possible solutions.  Finished with a sorting activity to determine best strategy to solve. 


alg II -  Unit review and quad application problems.  Check out the review guide to prepare for the test.


alg I -   We did another scatterplot, line of best fit, equation activity and added residuals to the mix.  Make sure you finish your parent function sketches by Friday.

Period 2 Alg II quadratics study guide

Looks like we will have 6-8 questions on our quadratics test.

On it, you will show that you can:

solve any quadratic equation - both real and imaginary answers
graph any quadratic equation
solve a quadratic application problem by developing a strategy (table, guess and check, create equation, graph) and find a solution
write an equation given the solutions of the function
be able to graph a function given the transformations to the parent function


Some application possibilities are:

finding the maximum height of a projectile
finding how long a projectile is in the air
building a pen from fencing to hold your elephants and snakes

1. Write an equation that has solutions x = -4, 6
2. solve:  x^2 = -8x -15
3. solve:  y =  2x^2 +19x + 24
4. solve:  x^2 -10x = 11
5. solve:  2(x+2)^2 = 22
6. Find domain and range for y = -x^2 +6
7. graph:  f(x) = -3x^2 + 12x -5
8. How high does a ball go up if its path is modeled by h(x) = -16x^2 + 160x   where x is horizontal distance and h is height.
9.   You have 1,000 feet of fencing to make 2 pens to hold animals.  What is the maximum area you can make from this amount of fencing.

Wednesday 10/ 17

alg II hp -  Big review day for our test on Friday.   We looked a little slow, especially on graphing and factoring.    Check out the guide and you can ask questions tomorrow.  See you then. 




alg II -   Did a bunch of whiteboard exercises to review the unit. Also looked at probelems #58, 60 in the text on p. 128.   Hw is p. 128  #39, 40.




alg I -  Small bit of review from yesterday's handout.  We also took notes on parent functions and did some practice on graphing when you realize that an equation is a parent function.
