Best ResponseYou've already chosen the best response.3since the function is periodic with period 12, f(43) = f(4312) = f(31), did u get this ?

Best ResponseYou've already chosen the best response.1I 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) ?

Best ResponseYou've already chosen the best response.3f(31) = f(3112) = f(311212) and so on...

Best ResponseYou've already chosen the best response.1Woah. Why would you subtract 12 twice or more times? And what do we figure out when we do that?

hartnn

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

Best ResponseYou've already chosen the best response.3more specifically \(f(x\pm n*12 )= f(x)\)

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

Best ResponseYou've already chosen the best response.3f(43) = f(31) u got this ?

hartnn

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

Best ResponseYou've already chosen the best response.1Okay I got everything except the f(7)

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

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

hartnn

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

Best ResponseYou've already chosen the best response.1sotheanswer coulve been 5 or 2?

hartnn

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

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

hartnn

Best ResponseYou've already chosen the best response.3for the same periodic function ?

hartnn

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

Adorkable

Best ResponseYou've already chosen the best response.1So it can be plus or minus?

hartnn

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

Best ResponseYou've already chosen the best response.1Okay. 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.

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