Hi again
x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.
If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.
Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8
I hope that's help !
Let the event 'has cancer' be C, and the event 'works for Ajax' be A.
P(C) = 0.0019. P(A) = 0.28
The events A and C are independent if P(C|A) = P(C).
P(C|A) = 0.0019 = P(C).
Therefore the answer is YES.

Answer:
integers ∪ [0, ∞)
Step-by-step explanation:
The floor function gives the largest integer not greater than the input value. For non-negative numbers, that is the integer portion of the number, as Jim says.
However, for negative numbers, the floor is one less than the integer portion of any number that has a non-zero fractional part.
floor(1.2) = 1
floor(0.2) = 0
floor(-0.2) = -1
floor(-1.2) = -2
For any integer, negative or otherwise, the floor function gives that integer value.
Jim is correct on the domain of all integers and positive non-integers.
