It is known that the odd function f (x) is a decreasing function defined on (- 1,1), and f (1-T) + (1-T & sup2;)

It is known that the odd function f (x) is a decreasing function defined on (- 1,1), and f (1-T) + (1-T & sup2;)

Since f (x) is an odd function, f (1-T & # 178;) = - f (T & # 178; - 1)
So the original inequality can be reduced to
f(1-t)
