In Exercises 1-2,
(a) use the Intermediate Value Theorem and the table feature of a graphing utility to find intervals one unit in length in which the polynomial function is guaranteed to have a zero.
(b) Adjust the table to approximate the zeros of the function to the nearest thousandth.
1. f (x) = x3 − 3x2 + 3
2. f (x) = 0.11x3 − 2.07x2 + 9.81x − 6.88
