Write your answer in fraction form. 3) (20x3 - 13x + 23) + (4x2 - 4x + 3) For each function, state the maximum number of extrema. Then find the zeros and the mulitplicity for each zero. 4) f ( x) = x - x2 5) f (x) = x3 -4x2 + 4x Use synthetic division. Write your answer in fraction form. 6) (2x# + 13x3 + 16x2 + 18) + (x+2) 7) (9x* - 27x3 + 3x - 13) +(x-3)
