According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 – 2x4 + 9x3 – x2 + 12?

Respuesta :

Answer:


Step-by-step explanation:

Given is an algebraic polynomial of degree 5.

[tex]g(x) = 3x^5-2x^4+9x^3-x^2+12\\[/tex]

Here leading term is p=3 and constant term is q =12

Factors of p are ±1,±2,±3

Factors of q are [tex]\frac{±1,±2,±3,±4,±6,±12} \\[/tex]

Possible forms of p/q will be the same for any other polynomial of degree 5 with leading term =3 and constant term = 12

Hence any other polynomial

[tex]g(x) = 3x^5+ax^4+bx^3+cx^2+12[/tex]

will have same possible zeroes of p/q, when a,b,c are rational.

Hence any polynomial of this type would have the same possible rational roots.

The answer is A, or [tex]f(x) = 3x^{5} - 2x^{4} - 9x^{3} + x^{2} - 12[/tex]

If the picture won't load, the correct equation is f(x) = 3x^5 – 2x^4 – 9x^3 + x^2 – 12

Just got it right on the quiz, hope this helps!! :)
