Question

If f(x) = 3x4 + 2x3 - x + 15, what would be the list of possible rational roots?

Answer 1

Answer: A. ± $\frac{1}{3} ,\frac{5}{3} ,1,3,5,15$

Step-by-step explanation:

± $\frac{1, 3, 5, 15}{1, 3}$

= ± $1, 3, 5, 15, 1/3, 5/3, 5$

Rearranging, we get:

= ± $\frac{1}{3} ,\frac{5}{3} ,1,3,5,15$
