f(x-1)=2x+3 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)?
已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x)
已知f(x+1)+2f(-x)=3x²+x,求f(x)
f(x+2)>=f(x)+2,f(x+3)
f(x)=x(x-1)(x-2)(x-3)(x-4) f'(1)=?
设函数f(x)满足f(x)+2f(1/x)=x,求f(x)
F(x)=3x^2+2x-1 求F(x+△x)-f(x)/ △x
f(X)=f(X+2)(x
f[(3x+2)/2x-1]=x^2-1,求:f(1),f(x)
3f(x)+2f(1/x)=2x,则f(x)=?
