In Exercises 1-2, use a graphing utility to graph the functions f and g in the same viewing window. Zoom out sufficiently far to show that the left-hand and right-hand behaviors of f and g appear identical.
1. f(x) = 3x3 - 9x + 1, g(x) = 3x3
2. f(x) = -1/3(x3 - 3x + 2), g(x) = -1/3 x3
3. f (x) = −(x4 − 4x3 + 16x), g(x) = −x4
4. f (x) = 3x4 − 6x2, g(x) = 3x4
