f:R→R_+ ,g:R→R_+   2f(x)=f(x−1)+g(x+1)  [g(x)]^2 =f(x−1)g(x+1)  f(−1)=1,g(1)=2,f(0)g(0)=?
f:RR+,g:RR+2f(x)=f(x1)+g(x+1)[g(x)]2=f(x1)g(x+1)f(1)=1,g(1)=2,f(0)g(0)=?

2f(0)=f(−1)g(1)=2⇒f(0)=1  [g(0)]^2 =f(−1)g(1)=2⇒g(0)=(√2)  f(0)g(0)=(√2)
2f(0)=f(1)g(1)=2f(0)=1[g(0)]2=f(1)g(1)=2g(0)=2f(0)g(0)=2

  2f(0)=f(−1)+g(1)=3=>f(0)=(3/2)    [g(0)]^2 =f(−1)g(1)=2=>g(0)=(√2)  f(0)g(0)=(3/( (√2)))
2f(0)=f(1)+g(1)=3=>f(0)=32[g(0)]2=f(1)g(1)=2=>g(0)=2f(0)g(0)=32
