A. For the polynomial function of the form f(x) = ax + bx + cx + d with the values given below, determine its features and sketch the function. Make sure to include: I All factoring work Table of intervals End behaviours B. An additional factor with a root (see below) is added to your equation, resulting in a degree 4 polynomial. How does the new polynomial's features and graph compare? a b C 2 12 -74 -180 (additional root) 2
