Find the zeros of f(x) = βx3 β 2x2 + 7x β 4. Then describe the behavior of the graph of f at each zero. A. 4, β1; As x β ββ, f β ββ. When β1 < x < 4, f < 0. At x = 4, f is tangent to the x-axis, so when x > 1, f β β. B. β4, 1; As x β ββ, f β ββ. When β4 < x < 1, f > 0. At x = 1, f is tangent to the x-axis, so when x > 1, f β ββ. C. 4, β1; As x β ββ, f β β. When β1 < x < 4, f > 0. At x = 4, f is tangent to the x-axis, so when x > 1, f β β. D. β4, 1; As x β ββ, f β β. When β4 < x < 1, f < 0. At x = 1, f is tangent to the x-axis, so when x > 1, f β ββ.
