Answer:
see explanation
Step-by-step explanation:
This is not a prime polynomial as it can be factored into polynomials of lower degree.
Given
x³ + 3x² - 2x - 6 ( factor the first/second and third/fourth terms )
= x²(x + 3) - 2(x + 3) ← factor out (x + 3) from each term
= (x + 3)(x² - 2) ←can be reduced further as a difference of squares
= (x + 3)(x - )(x +
)

We know that:
So, from the conditional probability, we can calculate:
Answer E.
First, let's simplify the inequality
The graph looks like this:
Notice that the white dot is placed above the -6, it is important to include it like that.
Now, as an interval:
