Question 16

Let $g(x)$ be a polynomial with leading coefficient $1,$ whose three roots are the reciprocals of the three roots of $f(x)=x^3+ax^2+bx+c,$ where $1\lt a\lt b\lt c.$ What is $g(1)$ in terms of $a,$ $b,$ and $c?$
  1. $\dfrac{1+a+b+c}{c}$
  2. $1+a+b+c$
  3. $\dfrac{1+a+b+c}{c^2}$
  4. $\dfrac{a+b+c}{c^2}$
  5. $\dfrac{1+a+b+c}{a+b+c}$
