1.设f(x)s是R上的奇函数,且满足f(x+2)=-f(x),当0≤x≤1时,f(x)=x,则f(3.5)=?

问题描述:

1.设f(x)s是R上的奇函数,且满足f(x+2)=-f(x),当0≤x≤1时,f(x)=x,则f(3.5)=?
2.若f(1/x)=1/(x+1),则f(x)=?

满足f(x+2)=-f(x),f(3.5)=f(1.5+2)=-f(1.5)f(1.5)=f(-0.5+2)=-f(-0.5)f(3.5)=f(-0.5)f(x)s是R上的奇函数,f(-0.5)=-f(0.5)当0≤x≤1时,f(x)=x,f(0.5)=0.5f(3.5)=f(-0.5)=-f(0.5)=-0.52.若f(1/x)=1/(x+1)=(1/x)/[1+1/x...
