Behavior of polynomial function

Start from second degree polynomials and then third degree... Change the parameters a, b, c, d, and e many times to check the following 1) What are the general characteristics of polynomial functions (Domain, range, continuity...) 2) The zeros of polynomial functions (their number, relation to the degree...) 3) The number of maximum, minimums, turning points with respect to the degree At the end answer the questions below
