Another page has been sweated over: Function Transformation
Please check it. There are lots of up, down, left, right, compress in y, stretch in x, ... etc ... so I may have easily got one or two of them the wrong way round.

Good page! I seem to be missing some cheese.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Thinking is cheating.
Why? Well imagine you are going to inherit a fortune when your age=25. If you change that to (age+4) = 25 then you would get it when you are 21. Adding 4 made it happen earlier.
Sorry, just being picky...
But all in all, it's a very fun page! It has great explanations and lots of examples. Great job!
