hey everyone these r my
answers wt abt urs hv i got
anyone rong plz discuss

How could F inverse x be equal to f(x)? :|

Yep, your answers are absolutely right. I got the same. Alas, I got a competitor who may snatch my distinction.

 

[hassam]

well zishi....beware i also got the same ansers.....lets see ni mechanics.....

 

[junaidaftab]

Guys, how is f inverse x equal to f(x). f square x was the identity function, not f(x)? :|

[sweetyrox]

Guyzz for da paraleelogram i did AB=CD ....wuld dat be wrong??

 

[intel1993]

@ksk: we r not saying it was difficlut actually but if u compare wth the last few papers it was tricky and tough..........................
till we were not sure abt our answere we assumed it to be difficult......................lolx........ :Yahoo!:

 

[ks136]

PLEASE

what please?

 

[junaidaftab]

How is f inverse x equal to f(x). tell me :|

 

[Moiz]

It was a very easy paper... I m expecting Full marks

yeah rite it wasnt that much difficult
bt when ans r nt exact (bt are in fration or decimals)
i wasnt sure that they r correct

past pprs trend showed that
this one is goin to be tricky

How is f inverse x equal to f(x). tell me :|

f(fx)=x
it means

f inverse x= fx

 

[junaidaftab]

We were supposed to find the inverse of the function f(x), not of the composite function ff(x) which is indeed an identity function. :|

no but u can do like this
e.g
if fx=y
then f inverse y= x
