Answer
$-8, -4, -2, -1, 1, 2, 4, 8$
Work Step by Step
RECALL:
The possible rational zeros of a polynomial function is given by $\dfrac{p}{q}$ where:
$p$ = factor of the constant term
$q$ = factor of the leading coefficient
The given polynomial function has:
constant term = $8$
leading coefficient = $1$
The factors of the constant term are: $\pm1, \pm2, \pm 4, \pm8$
The factors of the leading coefficient are: $\pm 1$
Thus, the possible rational zeros of the given polynomial function are:
$\pm 1, \pm 2, \pm 4, \pm8$
