55. A polynomial, f(x), has the following values:

f(-2) = -10

f(-1) = -6

f(0) = -4

f(1) = 2

f(2) = 18

Between which 2 consecutive integers, if any, must f(x) have a zero?

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

When x=0, f is a negative number; when x=1, f is a positive number. So x must be between 0 and 1 when f is equal to 0.
