Let f (x) be invertible function and let f ^(-1) (x) be is inverse. Let equation f (f ^(-1) (x)) =f ^(-1)(x) has two real roots alpha and beta (with in domain of f(x)), then :

Answer»

`f (x) =x ` also have same two rreal roots
`f ^(-1) (x)=x` also have same two REAL roots
`f (x)=f^(-1)(x)` also have same two real roots
Area of triangle formed by `(0,0), (alpha, f (alpha)), and (BETA, f (beta))` is 1 unit
