    1)f(x)+f(-x)=0

    f(x+3x4)+f(-x+3x4)=0

    f(x+12)+f(12-x)=0

    f(f(2) let cosx=t -1<=t<=1

    sinx2=1-t^2

    f(x)=t^2-1-at

    4ac-b 2) 4a=-6=-4-a 2 4=-1-a 2 4a = +-2 root 5

    b 2a=a 2 does not belong to -1< = t<=1 does not hold.

    So when t=1 -a=-6 a=6

    t=-1 when a=-6

    a=+-6

    f(2) is a bit puzzling, if f(x) here still satisfies the above question: "The periodic function f(x) is an odd function, and one of its periods is 3, f(

    , from the odd function we know that f(0)=0

    f(x)=-a=0,a=0!!And f(

    Obviously, it's not -1 at this point!

    Incomprehensible .........

    Because Chai Bi f(x) Lu Bu = f(x+4), -f(x) = f(-x) so f(-3) = f(-3+4) Sui Siju = f(1) = -f(-1) = -1

    f(x) is the odd scattering function of the vertical waiter.

    So f(1)=-f(-1)=-3

    f(x) is a periodic function with period 4.

    The fiber is infiltrated to. f(5)=f(1)=-3

    The problem is wrong, it should be f(1)=-1, otherwise it can't be solved.

    Because it's an odd function.

    The finch is f(-1)=-f(1)=1

    And because of the minimum positive period.

    is 3, and 101 to -1 is exactly (101+1) 3=34 cycles.

    F(101)=1

    The odd ash scatter function f(x) is a period of 4 and the period of the trembling period.

    f(-2)=-f(2), i.e. f(-2+4)=-f(2), then f(2)=-f(2), i.e. f(2)=0, so the answer is: 0

    Because f(x) is a periodic function with 5 as the period of the rubber disturbance, and f(-1)=1, f(-1+5)=f(4)=1

    f(x) is the Lie chain of the beam-empty odd function.

    So f(-x) = f(x), f(-4) = f(4) = -1

    It is known that the functions f(x) and x r are odd functions with a period of 4 in the cavity, and f(3) 1f(-1)=f(-1+4)=f(3)=1

    The number of odd circle digs f(-1)=-f(1)=1

    So Kai laughs f(1)=-1

    f(2013)

    f(2012+1)f(1)

I just answered it for someone else yesterday, and I copied it directly and changed it slightly, but you didn't have a third question. If you look at it in general, the approach is the same, very similar, but in fact, a question has been slightly changed. If you are interested, you can click on the third question I answered to take a look. >>>More

Let f(x)=ax squared + bx+c,,, because f(0)=1, substituting 0 into c=0, that is, f(x)=ax squared + bx, and because f(x+1)=f(x)+x+1, substituting f(x)=ax squared + bx into this equation, we get ax squared + (b+1)x+1=ax squared + (2a+b)x+a+b, and the solution of a=b=b+1 from the principle of constant eqation gives a=b=one-half. Therefore, f(x) = one-half x square minus one-half x I believe that the landlord has done the second question, and I wish the landlord learning progress.
