Precalculus thinking

This is what we do, Applied.
Area = Length * Width
- - makes sense right?

Precalculus find out whut the width is, and they know what the length is, so basically they come out with an equation like this..
y= (24-2x)(x)
y= 24 x-2x squ.
y= -2x squ. +24x

Assignment/Lil bit of notes.

Ex.1 (handout)
For monday : Pg A-4; 3,4,5

3 c) y=x^2+6x+4 --- this has a minimum(the bottom of the cup)
::to find vertex for sure

2nd.. trace.. minimum.

MAXIMUM.. DOWN..
MINIMUM UP..

Random Notes..

x 1 - linear

x2 - quadratic

x3 - cubic

x4 - quartric

x5 - quintic

NON LINEAR

A)Domain and Range
B)Function
C)Quadratic functions
D)Cubic functions

Do not post material to the blog without referencing!

.. stay in secondary school. Things in highschool.
Keep references, examples, images, videos, links, etc. SIMPLE.
You're teaching grade 11 classmates.

Be creative!

By the end of Fridays class, you should be able to answer questions like::
What is a function??
What is the domain of the pictured function?? Why?
Compare quadratic functions to cubic functions? etc.........
