f(x)-2f(-x)=2x^2-3x+2求f(x)的解析式

f(x+2)>=f(x)+2,f(x+3) f(X)=f(X+2)(x 已知f(x)满足2f(x)+f(1/x)=3x,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(-x)=-3x+1,求f(x) 已知f(x)满足f(x)+2f(1/x)=3x,求f(x) , f(x)=x^2+x (x ∫[f(x)/f’(x)-f^2(x)f’’(x)/f’^3(x)]dx ∫[f(x)/f'(x)-f^2(x)f(x)/f'^3(x)]dx 如题 已知函数f(x)=x^3+x^2-2x-x,f(1)f(2) 已知f(x)+2f(1/x)=x+2/x+3,求f(x) 已知f (x)+2f(-x)=x^3+x^2,求f(x) f(x)满足f(-x)+2f(x)=x+3,则f(1)等于 设f(x)={3x-1,x=0,求f(-x),f(x-2). f(x)+2f(-x)=3x+x的平方,则f(x)等于 f(x+1)+f(x-1)=4x^3-2x求f(x) 已知f(x+1/x-1)=3f(x)-2x,求f(x)
