1/ For each of the following polynomial functions, using the degree and the sign of the coefficient:
I) describe the behavior endlessly;
II) indicates the finite differences which
will be constant;
III) determine the value of the differences
constant finites.
a) y = x4 + 6 x3 + 11 x2 + 6 x
b) y = x3 + x2 - 4 x + 1
