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. (will mark brainliest)(plz answer quick) 2x^3+5x^2-8x-20=0

all possible roots:

+-1 , +-1/2, +-2, +-4, +- 5, +- 5/2, +- 10, and +- 20

solve for x

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:
