Find all the zeros of the polynomial function. Use the Rational Zero Theorem, Descartes's Rule of Signs, and possibly the graph of the polynomial function shown by a graphing utility as an aid in obtaining the first zero. fx)-x-3x-13x + 15 The zeros of the function are (Use a comma to separate your answers as needed.)
