since the function is periodic with period 12, f(43) = f(4312) = f(31), did u get this ?

I think so. So if for example in the same context if the question was f(79) then it would be f(79  12) = f(67) ?

f(31) = f(3112) = f(311212) and so on...

Woah. Why would you subtract 12 twice or more times? And what do we figure out when we do that?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
because for every interval of 12, the function has same value.... so if i add or subtract 12, the value of function is same \(f(x\pm 12 )= f(x)\)

more specifically \(f(x\pm n*12 )= f(x)\)

n can be any natural number .

hartnn Group TitleBest ResponseYou've already chosen the best response.3
so, f(43) = f(4312) = f(31) = f(3112) =.... do this till u get something you know the value of.

not quite sure im understanding.

f(43) = f(31) u got this ?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
well, i'll write out steps, see if u get it \(f(43)=f(4312)=f(31)=f(3112)=f(19)=f(1912)=f(7)=2\)

Okay I got everything except the f(7)

Because 1912 equals 7 but, then 712 is equal to 5

hartnn Group TitleBest ResponseYou've already chosen the best response.3
but u already have f(7) = 2 so u get f(43) = 2
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
and yes, f(5) also equals 2

sotheanswer coulve been 5 or 2?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
no, not 5 . f(43) = f(7) = 2
 2 years ago

Adorkable Group TitleBest ResponseYou've already chosen the best response.1
hmm. Can we try another example please? say f(1)?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
for the same periodic function ?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
ok, f(1) = f(1+12) = ?
 2 years ago

Adorkable Group TitleBest ResponseYou've already chosen the best response.1
So it can be plus or minus?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
its f(11) yes, + or 12 ...
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
f(1) = f(11) = 9

Adorkable Group TitleBest ResponseYou've already chosen the best response.1
Okay. I have an idea of what youre talking about. I'll try this one and can you see if it is correct for me? Same function.
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
yes, try it ..

Adorkable Group TitleBest ResponseYou've already chosen the best response.1
Would it be f(95)=f(11)=9 so far am i correct?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
yes, ver correct :)
