4. (12 points) For the polynomial P(x) = x4 - x3 - 6x2 a. Find its zeros and the multiplicity of each zero (Hint: Consider factoring first!) b. Describe the expected behavior of the graph at each of its zeros based on the multiplicity of the zero. c. Describe the expected end behavior of the graph based on its degree and the sign of its leading coefficient. Degree of P(x) = Sign of Leading Coefficient: Expected End Behavior: x - 0 y -> x - - 00 y ->
