Using the Factor Theorem, the equation for the graphed polynomial is: y (x) = 0.125 (x + x - 14x - 24). Process for Finding Rational ZeroesUse the rational root theorem to list all possible rational zeroes of the polynomial P (x) P ( x).Evaluate the polynomial at the numbers from the first step until we find a zero. Repeat the process using Q(x) Q ( x) this time instead of P (x) P ( x). This repeating will continue until we reach a second degree polynomial. For example, consider. f_f(x)=4x^5-5x^3 , but also f_f(x)=3 Solve Now Now that we know how to find zeros of polynomial functions, we can use them to write formulas based on graphs.
