Today’s plan in math
- Test Review
- Practice Test Questions

First we started the class of with Mr.Max handing out the review questions for the test. Then Mr.Max started putting up the review for the test. The unit we are reviewing for is Non Linear Functions.
Test Review – Non Linear Functions
1. Mechanics- For this section we should know the following things.
- Functions/relations
- Domain/range
- Calculator Stuff (Tracing, calculating, windows, zooms, tables, graphs, intersections, etc.
Graphmatica Printing
-First you open up graphmatica.
-Put in your equation, press enter.
-Then at the top left hand corner of the screen you should see a button called “copy graphs”.
- Click on it, and now you have copied your graph.
-Now open up word.
-Right click and select paste.
- Now you can print!
(**DO NOT HIT PRINT SCREEN ON GRAPHMATICA always print off word, if you do print off graphmatic I suggest hiding from Mr.Max.)
2. Quadratics “Actual important stuff in the course”
Y-k=a(x-h) ^2 vertex opening form
y=ax^2+bx+c=standard form
(H, K) = the vertex of a parabola

How to find the vertex of a parabola.
1. Graph the parabola on your calculator.
2. Press 2nd trace
3. Next select minimum or maximum, and press enter.
X=linear (no Curve)
X^2= Quadratic ( 1 Curve)
X^3=Cubic(2 Curves)
X^4=Quartic(3 Curves)
X^5 Quintic (4 Curves)
Cubics
· Box volume or relative min/max problems.
· Cubic Functions are all in this form y=ax^3+bx^2+cx
Exponentials
· No “e” questions
· You will have to use exp reg to create y =a.b^x
*Before Mr.Max had to leave he had a “crazy idea”, this crazy Idea was instead of us having our test tomorrow in class, and we would take home our tests and hand them in on Friday! The next scribe is Bass.
