f(x)=(2x-3/3x-2)* Inx 当x趋向于1是无穷小吗

已知f(x)定义域为(-2,2) 且f(x)={2/(x+3)+In(2-x)/(2+x),-2 f(x+2)>=f(x)+2,f(x+3) 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-1)(x-2)(x-3)In(1+x)导数零点个数请详细些 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) 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) f(x-1)=x^2-2x+3(x f(x)=x^2+2x-3(x f(x)=5x+3 f(x)=5x f(x)=x+2x+1 f(x)=5x+3 f(x)=5x f(x)=x+2x+1
