Question
In Problems 33–38, find the bounds to the zeros of each polynomial function. Use the bounds to obtain a complete graph of f.
34. f(x) = 3x3 – 2x2 + x + 4
33. f(x) = 2x3 + x² – 1
35. f(x) = x3 - 5x? – 11x + 11
36. f(x) = 2x³ –x² – 11x – 6
37. f(x) = x* + 3x³ – 5x² + 9
38. f(x) = 4x* – 12x + 27x – 54x + 81
