Plz fast. it's pre calculus. this is the only day i get to spend time with my baby sister. fast. will mark brainliest. which of the following is a root of the polynomial shown below? look at the graph of the function and find the solutions. f(x)=x^3+2x^2-x-2 a.1 b.0 c.3 d.2 which of the following represents the set of possible rational roots for the polynomial shown below? this question is a review from algebra 2. remember that possible rational roots take the form of p/q. where p is a factor of the constant and q is a factor of the leading coefficient. 2x^3+5x^2-8x-20=0
