Answer:

D

Explanation:

one way to write a quadratic equation is using the y = (x-s) (x-r) where r and s are positive zeros. another way to solve this and think about it would be to plug in your points and equate both sides. example:(3,0) (8,0)0 = (3-8) (3-3)0 = 00 = (8-8) (8-3)0=0

the answer is D. this is because in order for the brackets to equal zero, you have to have a negative number inside.
