Поздрав,
имамо задатке и неке вести на http://imocompendium.com/phpBB/viewtopic.php?t=119
Задаци изгледају средње тешки, наши према прелиминарним информацијама нису лоше урадили, али координација је тек сутра.

Mislim da bi znao 2 zad.
Dobio sam
f(x)=x^2
Naravno ne nagadjanjem
Ako treba mogu i da ispisem svoje resenje

evo mog resenja nadam se da je tacno:


Ako uzmemo da je  y=f(x)
dobicemo  f(2f(x)) = f(0) + 4f(x)^2
odnosno  f(2y)=f(0) + 4y^2 (*)
ako bi uzeli da je  x=0 i  y=f(0)
dobili bismo  f(2f(0)) = f(0) + 4f(0)^2
odnosno  f(2y)=y + 4y^2
smenom  m=2y dobijamo  f(m)={m\over 2} + m^2
kada bi to zamenili u pocetnu jednacinu  f(f(x) +y) = f(f(x) - y) + 4f(x)y
dobili bismo da je  y=0 a posto smo na pocetku uzeli da je  y=f(0)
dobijamo da je  f(0) = 0
iz (*) sledi da je  f(2f(x) = 0 + 4f(x)^2
odnosno  f(x) = y sledi  f(2y) = 4y^2
pa je  f(y) = y^2
sto je tacno i posle direktne provere

Па ако су вам свима оваква решења... онда машала. Бојим се да ово скроз не ваља још од трећег реда. Не мора за свако y да ти постоји x тако да је y=f(x), а још мање мора да постоји 0 тако да је y=f(0) blink.gif

Па рек'о си да је оно горе тачно, а то је исто као да си га и сам онако ''урадио'' laugh.gif Не верујем да има готових резултата, у ствари ја долазим овамо у нади да ћете нешто сазнати пре мене biggrin.gif Ове моје форумџије кажу да изгледа да Јевремовић добија опет злато, Теодор и Радојевић сребра, а остали бронзе.

Chestitam svima. Stvarno svaka chast...


--------------------
And as we wind on down the road
Our shadows taller than our soul
There walks a lady we all know
Who shines white light and wants to show
How everything still turns to gold
And if you listen very hard
The truth will come to you at last
When all are one and one is all
To be a rock and not to roll


Svi me žele, a ja sam nedodirljiv!
