Not Much...

Very little (read: nothing) happened in the way of instruction on my scribe day so unfortunately I have very little to write about for my blog post...

At any rate, here are a few interesting links:

http://www.math10.com/en/math-games/3D-logic.html

This is simply a 3d logic game - just connect the squares. I thought it would be pertinent to our math glass since logic skills and mental three-dimensional rotation skills are closely related to mathematical aptitude.

Also for the more verbally inclined:

Just a simple vocabulary test, only with a little extra feature: for every word you get correct, the site will donate 20 grains of rice though the UN World Food Bank to help end world hunger.

Also for the budding autodidacts among us:

Enjoy!!!

adding to Amy's post

So as you all know, today Mr. Max taught us about logs!



He began with explaining to us what a log was, and it is really just another type of notation that can be used to express things such as really big numbers and it is the inverse of an exponential function.



He also explained what the parts of a logarithmic function were.

In the function:

x = b^y --> x is the argument, b is the base, and y is the argument.



In the second screen shot, he then went on to show us how to write exponential funtions in logarithmic notation and vice versa.



In the third screen shot he showed us a logarithmic function that does not exist. This is because if you try to sub in a +2 for the x value you wont arrive at a -4 and if you sub in a -2 for x, you will end up with a +1/2

On the fouth and fifth slides he graphed examples of logarithmic functions, and on the following slide he gave us a list of 8 common log properties.



Exercise 20 #'s 1-12 and Exercise 21 #'s 1-8 are due for tomorrow!



Hope these notes were helpful and have a great day!

Hand In Assignment

Exponential Functions

Hey class,
So today Mr. Max taught us a few things on Exponential Functions, beginning with identifying some of the parts of a function and some useful terms that we should iNvEsTiGaTe
:


*this picture above shows what an increasing or decreasing graph would look like


*He also explained to us what a discontinuous function would look like







and here he explained the one to one property, this is a property in which there can only be one corresponding domain value per output value






He also made us a list of perfect squares and cubes that we should try to memorize, and our assignment is posted above along with the blog question that he will have posted for us at the end of the day. Have a great Easter weekend everybody!!
