    Let us assume f (x) = 2x - 5

    f⁻¹ (x) = (x + 5) / 2

    f (f⁻¹ (x)) = 2 ((x + 5) / 2) - 5 = x

    f⁻¹ (f (x)) = (2x - 5 + 5) / 2 = x

    The domain of a function is the range of its inverse and vice versa

    The range of a function is the domain of its inverse and vice versa

    Therefore, statements A, B, D and E are true
