alg II Hp - if you missed class, we reviewed graphing rational functions and were able to try one        more d=rt problem;  perf task on Thursday



alg I P - study because you have a unit test tomorrow on exponential functions!   please look at the review guide that is in a previous post.

alg II Rational Function Review Guide

Make sure you are from period 1 or 2 if you are reading this post.



Here is a rough study guide for the rational function test.

2 graphing problems - 1 parent, 1 non-parent


1 writing an equation from a graph

1  stating domain and range of a rational function

3 word problems; probably 2 with d=rt and 1 with variation - check out your POUs that you should have back now

1 writing equation of a non parent function when you know the zeros and asymptotes

2-3 rational function equations that you will have to solve.  look for unreasonable solutions


Here are a few samples I thought of.

1. Create a rational function that has the given lines as asymptotes.
1. y = -3, x = 1, and x = -4

2.  what is the domain of the parent rational function that has been v. stretched by 3, reflected over the x-axis, shifted 4 to the left and down 3?  Write the equation to show this function.

3.   solve  2/(x(x+1)) = 1 + (2/ (x+1))

4.  Julien can mulch a garden in 20 minutes.  Together, Julien and Remy can mulch the same garden in 11 minutes.  How long will it take Remy to mulch the garden when working alone?


5.  graph:  y = (x-4)(x+2)/ ((x-7) squared)


6.  A disinfectant kills germs pretty quickly.  After 1 second, there are 1000 germs but after 5 seconds there are only 40.  When will there be only 1 germ?

I bet there are most just like these in the hw that we did (some of us did).

friday 2/26

alg II Hp -  if you missed today, we went over the d=rt problems from Thursday and worked through 2 solving rat, fun. problems.  Perf task next week!

alg I P -   no hw but if you missed today, we had a writing prompt, loteria and looked at another word problem that involved exponential functions

alg I exponential test review guide

There is a test coming up on Exponential functions.



1 graphing an exponential function; know how to make a table a plot the points


2 scientific notation problems; one will involve operations with very large/small numbers


Some of the rules of exponent problems from the quiz will be on this; probably 3

1 problem on comparing 2 money models- (we did this twice in class)''

2 word problems on decay/ growth models

1 problem going from a data set/ table to equation

2 simplifying radicals


You don't have to memorize the formulas but you will have to know that growth is 1+r and decay is 1-r.
here is a link to a video on rules of exponents

https://www.youtube.com/watch?v=wsaH5CARIHI


here are a few samples:
1.  simplify the square root of 24 plus the square root of 54
2.  a town of 10000 grows at 1%.  How many people live there in 8 years.
3.  graph y=5(3) to the x.
4.  (3x)(-4x) =
5.  what is anything to the zero power?
6.  what is 5 to the negative 2 power/

thursday 2/25

alg II Hp - no hw


alg I P -  no hw; test is coming - start studying!!

Wed 2/24

alg II Hp - there were 4 problems assigned from 7.5 section of the textbook.  I can't remember which ones but there were 2 proportion problems and 2 where you would most likely fraction bust out the problem.  See me for more details.


alg I p -   the hw is from the Holt book (red book) p. 713-4.  If you were in class, you should have copied them down.  For period 4, it was #21-25, for period 5 and 6 I changed it to #31-36.

monday 2/22

alg II hp - finish the work from 7.4  p. 388 #8,9, 20, 22, 32, 45


alg I p - finish the linear vs exponential handout

friday 2/18

alg II hp -  period 1 you have your quiz on monday, period 2 no hw


alg I p - hw packet due on monday #6-9 from p. 751 Holt, handout about exponential functions

wednesday 2/17/ quiz info

I am out on Thursday at a conference but you can email me with any concerns.


alg II hp -  text big ideas  p. 380 # 3,5,10,15, 19-22

Friday quiz has 5 problems - 2 graphing, 1 complex fraction, 1 variation word problem, 1 mult or divide rational expression



alg i p - you should have finished your handout in class but if you didn't, turn it in ASAP

tuesday 2/16

alg II hp =  ish the problems from the board today 3,5,7,9,11  graph each rational function


alg I p  - finish 6-9 in Holt book p. 751

videos for rational function unit - alg II hp

Here are some videos I scrounged up that match this unit pretty well.

In addition to the videos, I have a general plan for hw for this unit

Unit 6Rational

Functions

7.1) 5, 7, 10, 12, 13, 14, 19, 22, 32, 33

7.2 I) 6, 8, 10, 14, 17, 18, 2124

7.2 II) 29, 31, 32, 35, 38, 40, 43, 44, 48, 50, 55

7.3 I) 3, 5, 10, 15, 18, 19, 21, 22, 23

7.3 II) 27, 32, 34, 38, 42, 43, 44

7.4 I) 8, 9, 12, 15, 16, 20, 22, 23

7.4 II) 27, 28, 29, 36, 42, 44, 46, 51, 54

7.5 I) 8, 9, 10, 11, 13, 14, 16, 18, 23, 25, 27, 30

7.5 II) 33, 34, 42, 43, 48, 50, 51, 57

I could, of course, change it at any time but this was suggested by the calculus teacher and I can see us doing something very close to this..
