f(x)=2f(2-x)-x^2+8x-8
f(X)=f(X+2)(x
f(x+2)>=f(x)+2,f(x+3)
x-2 ,X>=0 f(x)=f[f(x+5)],x分段函数f(x)= x-2 ,X>=0 f[f(x+5)],x
f(2x-1)=x2+8 求f(x)
F(X)满足F(x)+2f(x分之1)=3X,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)?
设函数f(x)满足f(x)+2f(1/x)=x,求f(x)
已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x)
f(2-x)=f(x)
F(X)=2X^3+6X^2-8X计算:(1)F(X)•(-2X);(2)2F(X)-4X
f(x)=x/(x^2+1)
