1. The first polynomial is a quartic function with one real root and two complex roots, rising on both ends. 2. The second polynomial is a quartic function with four real roots, rising on both ends. 3. The third polynomial is a cubic function with three real roots, falling to negative infinity on the left and rising to positive infinity on the right.

ACTIVITY 3: SKETCH ME \( \begin{array}{l}\text { Sketch the graph of the given } \\ \text { polynomial functions. }\end{array} \) 1. \( y=x^{4}-2 x^{3}-7 x^{2}+8 x+12 \) 2. \( y=(x-2)(x+2)(x-3)(x+3 \) 3. \( y=(x+2)(x-1)(x-5) \)
