wtf... nice name 

Spoiler:

Tagalog pun/inside joke... ziraulo  -->  zira ulo ---> zira/sira (literally means broken) and ulo (means head) ---> Filipino term sira-ulo (lit. broken head/brain/or somewhere along those lines) usually used when someone intentionally does something stupid just for fun (positive way of using), is just plain retarded(negative) or a bastard/jerk(negative)

sorry... someone had to explain

hehe, thanks! although, of the given meanings, i prefer the first.

Compound function? I was thinking it was a function of a function, but that's a composite function. [runs off to check]

EDIT: Oh, I see. It is the same thing. Then, I shall provide you with an example.

Let f(x) = x² + 3x + 2, and let g(x) = 2x - 1. A compound, or composite, function is that which operates on another. For instance, if you evaluated f(2), you would just put 2 in for all the x in the function and evaluate. (2² + 3(2) + 2 = 12)

For the compound function f(g(x)), you would do a similar thing, but you would insert g(x) for all x in f(x). So,

f(g(x)) = f(2x - 1)
          = (2x - 1)² + 3(2x - 1) + 2
          = 4x² - 4x + 1 + 6x - 3 + 2
          = 4x² + 2x.

The compound function g(f(x)) will work similarly.

Oh, come on. It's not that bad. You should see the stuff I'm learning now. That will really make your head asplode.

Complain when you get to integrations....

B2T, btw.

[mangaluva]

I did all that. I failed at it. There's a reason I didn't take Advanced Higher Maths.

[Rellik]

why use such a confusing example if you are going to talk about functions? 

P.S i understand your post but why use such big(ish) equations.. when something like x+1 is more than enough

Yep, I think we have one, but this is for those who need math questions answered, or needs homework help or something like that. I dont know where to put this topic, so I stuck it here.

My question:
How do you write a compound function?

you see my friend, there's something in the internetz called Yahoo Answers - im sure secondary school level maths can get you answers in like 2 seconds xD


@newcomers - welcome to the red panda filled DCTP forums

Yes, but such a simple example would have been too boring (I'm a math major, if you're curious).
