Intro+to+Polynomial+Functions


 * Tuesday September 27th, 2011**


 * We discussed the applications of Piece-wise Functions; such as in the UN population projections graph.
 * In order to re-create the graph effectively, it had to be broken into separate parts. Each one representing a different function.
 * From these parts, equations can be made, through the application of transformations.
 * If the equations are close to the real graph, and the domain is restricted properly for each new piece of the function, the graphs should match, with no discontinuities.


 * Today, we also discussed the answers to the Unit 1 test, which can be found on a separate page. (Thanks Katie!)
 * We also worked on the 4x4 factoring square, which displayed the concepts from Grade 11 functions for factoring.
 * Finally, we were given the factoring practice sheet to remind us of last year's work.


 * Ex.** Factor:

x^2 + 6x + 8 ... ... ... ... ... ... ... 6x^2 - 11x - 7 = (x+2) (x+4) ... ... ... ... ... ... ... = (3x-7) (2x+1)

Some good examples for Factoring can be found on the following links.
