Define the function f(x)=2x/(1−x^2). Find the number of distinct real solutions of the equation f^(5)(x)=x.

  • math -

    This is ambiguous notation. Do you mean

    5th power of f(x)
    5th derivative of f(x)
    f(f(f(f(f(x)))))

    Hard to say from what is here.

  • math -

    i mean f^(5)(x)=f(f(f(f(f(x))))).
