Find the zeros of f(x) = -x3 - 2x2 + 7x - 4. Then describe the behavior of the graph of fat each zero. O A. 4, -1; As X —-0,— -^. When -1 < x < 4,f< 0. At x = 4, fis tangent to the x-axis, so when x > 1,8-5 O B. -4, 1; As x —,—-. When -4 0. At x = 1, fis tangent to the x-axis, so when x >1,1 - - 0 C. 4. -1; As x—--.f — . When -1 0.
