已知奇函数f(x)=-x^2+2x(x>0);0(x=0);x^2+mx(x0);0(x=0);x^2+mx(x已知奇函数f(x)=-x^2+2x(x>0);0(x=0);x^2+mx(x0);0(x

已知奇函数f(x)=-x^2+2x(x>0);0(x=0);x^2+mx(x0);0(x=0);x^2+mx(x
已知奇函数f(x)=-x^2+2x(x>0);0(x=0);x^2+mx(x0);0(x=0);x^2+mx(x

已知奇函数f(x)=-x^2+2x(x>0);0(x=0);x^2+mx(x0);0(x=0);x^2+mx(x
f(-x)=-(-x)^2+2(-x)
f(x)是奇函数
所以f(x)=-f(-x)=x^2+2x
m=2
画函数f(x)图像,在[-1,1]上单调递增
只需-1

-1<|a|-2小于1所以a大于等于-3小于-1或大于1小于等于3
