Function Transformation

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.

Cheers!

Re: Function Transformation

Hi MathsisFun;

Good page! I seem to be missing some cheese.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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!
