Consider the following.
f(x) = x - 5x2 + 5
(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. (Select all that apply.)
0[-2, -1] /
0[-1, 0] /

0 [0, 1]
0 [1, 2]
0 [4, 5] /
(b) Adjust the table to approximate the zeros of the function to the nearest thousandth. (Enter your answers as a comma-separated list. Round your answers to three
decimal places.)
