Answer:
srry man i suck at civics, but i think it is B?
Step-by-step explanation:
The x-axis intercepts are the roots of the polynomial. So, the roots are x = - 2, x = - 1 and x = 3.
Therefore, the polynomial can be factored as:
(x - (-2)) * ( x - (-1) ) * (x - 3) = (x + 2)(x + 1)(x - 3).
Answer: (x + 2) (x + 1) (x - 3)
R = {10; 15; 20}
S = {20; 25}
R U S = {10;15; 20; 25;
