请写出解题过程关于函数的问题请写出解题过程：x=3
f(-1/2)=1/2f(3)+1
x=-1/2
f(2/3)=1/2f(-1/2)+1
x=2/3
f?
最佳回答
x=3
f(-1/2)=1/2f(3)+1
x=-1/2
f(2/3)=1/2f(-1/2)+1
x=2/3
f(3)=1/2f(2/3)+1
=1/2(1/2f(-1/2)+1)+1
=1/4f(-1/2)+3/2
=1/4(1/2f(3)+1)+3/2
=1/8f(3)+7/4
f(3)=2

f(3)=1/2f(2/3)+1
f(2/3)=1/2f(-1/2)+1
f(-1/2)=1/2f(3)+1
则
f(3)=1/2f(2/3)+1
=1/4f(-1/2)+3/2
=1/8f(3)+7/4
f(3)=2
