For each function: (1) determine the real zeros and state the multiplicity of any repeated zeros, (2) list the x-intercepts where the graph crosses the xaxis, and (3) describe the end behavior. 1) f(x) = x3 + x2 4x 4 2) f(x) = x4 8x3 20x2 16x y 3) f(x) - -x' + 5x - 5x -5x + 6x 4) f(x) - x - 5x 5) f(x) - -x3 - 2x + 3x -2-Divide. Write your answer in fraction form. 6) (8x4 - 21x3 - 18x] + 15x + 25) + (x - 3) 7) (6x] + 3x - 12) + (x + 1) 8) (3x] - 2x - 9) + (x - 3) 9) (6x4 + 19x3 + 22x2 + 23x + 2) + (x +2) 10) (6.x3 + 23x3 + x + 22) + (x +4)
