not a how-to series, but these are the two relevant pages from my two bound notes on this topic. hopefully they are of use.

[the second page i believe is more detailed and useful]

those notes are beautiful

[onlyfknhuman]

awesome, do you have any notes on absolute values 

[fredrick]

mapping way is better

[xers]

Yes, but its more time consuming. This will save a lot of time in multiple choice questions.

just a thought: on the sixth line down, it says that a dilation by factor '1/a' from the x-axis is f(x)->af(x) and it says for a dilation by factor 'a' from x-axis f(x) -> af(x). shouldn't the first be the reciprocal instead... they cant both be right....
i may be just confused... any help would be appreciated :S
otherwise, awesome notes Mao! keep up the good work!

yeah, that was a bit I wrote to myself [possibly incorrectly] in a way that I understands it.

let , dilating by '1/a' would create , hence

as I said, it's probably only in a way that I understands it

[mikola1989]

ah, but doesn't dilating by '1/a' create ? resulting in ...
just like dilating by 'a' creates  , resulting in

exactly.
I had 'f(x)' representing 'y', no idea why I did that though. [it was probably me at some 3 am morning... a lot of my bound notes were done at those times]
