Well this unit overall made me dizzy. I kept mixing up the transformations -- I still do sometimes... :\ I haven't gotten the hang of Trigonometric Modelling so I'll go practice that. (As a matter of fact, I'm working on one as I type this up.) Remember, reciprocal functions

**are not**the same as inverse functions! Hmmm, I thought the easiest part of the unit was graphing absolute values. Batman function! :D

Anyway, I'm glad this unit's just about over and done with because that was way too much graphing for me. XD Too bad I have feeling I'm not with graphing just yet, sigh.

A review of some sort:

**A**f(

**B**x-

**C**) +

**D**:

**A**- stretches or compresses the

*y-coordinates.*

**B**- stretches or compresses the

*x-coordinates.*

**C**- shifts the graph

*left or right.*(Watch the sign of C!)

**D**- shifts the graph

*up or down.*

*y-coordinates*are multiplied by (-1) causing a reflection in the a-axis.

*x-coordinates*are multiplied by (-1) causing a reflection in the y-axis.

__Even functions:__The function is symmetrical about the y-axis.

__Odd functions:__The function is symmetrical about the origin.

__Inverses:__f

^{-1}(x)

**undoes**whatever f(x) did. (x and y values pretty much just switch places)

__Reciprocals:__Find invariant points where y= -1 and 1

*first!*

**Stretches before translations!**

**Stretches before translations!**

**Stretches before translations!**

I hope I got those right. I don't really have much confidence in myself when it comes to math. XD If you spot anything, drop me a sweet little comment! You can always view past slides, scribes, or deliciously informative links if you need more on Transformations. Good luck to everyone on the test! But luck's only a small part of it so remember to study, study, study!
