### BOB the BUILDER

I believe that everything that we learn in life is taught in chapters, and sooner or later we need to take all those chapters and make a conclusion. This is what the unit TRANSFORMATIONS felt like. It felt like I needed to go back try to remember how to graph and do questions regarding transformation.

Again "stretches before translations" stuck in my head.
DABC made an appearance in our unit again. I learned that:

D- Shifts graph LEFT to RIGHT
A- STRETCH OR COMPRESSION on Y coordinate
B- STRETCH OR COMPRESSION on X coordinate
C- *WATCH THE SIGN* shifts graph LEFT OR RIGHT

I was happy when I finally understood the difference between a inverse functions and reciprocal functions. I just need to remember that it is an INVERSE is when you switch the x and y coordinates. Reciprocal functions however comes with the invariant point (always -1 and 1), then the roots (for the asymptotes) then the biggering and the smallering.

As for the odd and even functions I get that the odd functions are symmetrical over the origin, and even functions are symmetrical over the y-axis. The only thing that's making me feel a little restless is the equation part of it. (like how when and where you subsitute things)

Other than that this unit was OK. Not great, not bad just mediocre.
Good luck on the test!!

The picture below is me pushing the rock, Mr. K behind me helping and behind him is the class. This just goes to show, no one person can defeat the mountain alone. Thanks guys.

Awwww, haha that's such a nice picture and meaning behind it. We're one big giant math family :D

Hey I loved your picture! It sends such a good message to us all and let's us know that we are not alone. Whoa! Giant Fuzzy feeling! haha :P

DID YOU MAKE THAT YOURSELF!?

Nice.

Hey Melk!

Two things:

(1) When when transforming functions of the form....

y = AfB(x-C) + D

D shifts the graph UP or Down, not sideways.

(2) I LOVE that picture! It made me feel the same way the other folks here have. That's a great way to "brand" your BOB. ;-)
