Example 4 - Find a zero of the polynomial p(x) = 2x 1 - Examples

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.f(x) = x^3 - 3x^2 - 6x 8The zeros of the function are (Use a comma to separate your answers as needed.)
