      A cubic function is a third degree polynomial function. There are also fourth, fifth, sixth, etc. degree polynomial functions. To get an idea of how these functions look, we can graph the first through fifth degree polynomials with leading coefficients of 1.

      The constant coefficient is the negative product of the roots for a cubic. In general, this coefficient is either the positive or negative of the product of the roots for any polynomial. The sign depends on the degree of the polynomial – if it's even, the sum is the positive one, otherwise it's negative.

      Investigation on the Roots of Polynomials. Let’s review by finding the roots of quadratic functions. Look at the graph of . Use completing the square or the quadratic formula to verify the solutions you found on the graph. Now, we will try to find roots of polynomials of larger degrees. Let’s start with the cubic polynomial .
