Resposta
To find the rational zeros of the polynomial \( f(x) = x^3 - 13x^2 + 47x - 35 \), we can use the Rational Root Theorem. This theorem states that any rational zero, expressed as a fraction
, must have
as a factor of the constant term and
as a factor of the leading coefficient.For the polynomial \( f(x) = x^3 - 13x^2 + 47x - 35 \):- The constant term is
.- The leading coefficient is
.The factors of
(constant term) are:
The factors of
(leading coefficient) are:
Thus, the possible rational zeros are:
Therefore, the correct answer is:C.
