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?
 one year ago

hartnnBest 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 .

hartnnBest 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 ?
 one year ago

hartnnBest 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)

AdorkableBest ResponseYou've already chosen the best response.1
Because 1912 equals 7 but, then 712 is equal to 5
 one year ago

hartnnBest ResponseYou've already chosen the best response.3
but u already have f(7) = 2 so u get f(43) = 2
 one year ago

hartnnBest ResponseYou've already chosen the best response.3
and yes, f(5) also equals 2
 one year ago

AdorkableBest ResponseYou've already chosen the best response.1
sotheanswer coulve been 5 or 2?
 one year ago

hartnnBest ResponseYou've already chosen the best response.3
no, not 5 . f(43) = f(7) = 2
 one year ago

AdorkableBest ResponseYou've already chosen the best response.1
hmm. Can we try another example please? say f(1)?
 one year ago

hartnnBest ResponseYou've already chosen the best response.3
for the same periodic function ?
 one year ago

hartnnBest ResponseYou've already chosen the best response.3
ok, f(1) = f(1+12) = ?
 one year ago

AdorkableBest ResponseYou've already chosen the best response.1
So it can be plus or minus?
 one year ago

hartnnBest ResponseYou've already chosen the best response.3
its f(11) yes, + or 12 ...
 one year ago

AdorkableBest 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.
 one year ago

AdorkableBest ResponseYou've already chosen the best response.1
Would it be f(95)=f(11)=9 so far am i correct?
 one year ago

AdorkableBest ResponseYou've already chosen the best response.1
Okay! Thank you once again so much for your patience and time!! Im going to best response all your answers!

AdorkableBest ResponseYou've already chosen the best response.1
Thats impossible. Lol. Sorry but thankyou!
