possible rational zeros=Factors of the constant termFactors of the leading coefficient
List the factors of the constant term and the leading coefficient of the given function.
Factors of the constant term, -4: +-1, +-2, +-4
Factors of leading co efficient, 1: +-1
possible rational zeros=Factors of 4Factors of 1
=+1,+2,+4+1
consider each number is numerator an divide it by each number in the denominator.
Possible rational zeros= +-1, +-2, +-4
Therefore, the possible rational seros of f(x) are
+-1, +-2 and +-4
