With this factored form, you can change the values of the leading coefficient a and the 5 zeros \( z_1, z_2, z_3, z_4 \) and \( z_5 \). You can explore the local behavior of the graphs of these polynomials near zeros with multiplicity greater than 1.
Once you finish this interactive tutorial, you may want to consider a self test on graphs of polynomial functions.
