Answer:
A
Step-by-step explanation:
A is biased because those people at the grocery store will most likely like that grocery store, since they went there to shop in the first place.
B, C, and D are not biased because there is no correlation between the grocery store and the survey questions.
x = - 2 and x = 3
to find the zeros set f(x) = 0
3x² - 3x - 18 = 0
divide through by 3
x² -x - 6 = 0
(x - 3)(x + 2) = 0 ⇒ x = - 2 and x = 3 are the zeros
According to my calculations it should be 0.18.
