Answer:
9
Step-by-step explanation:
6n = n² - 27
n² - 6n - 27 = 0
n² - 9n + 3n - 27 = 0
n(n - 9) + 3(n - 9) = 0
(n - 9)(n + 3) = 0
n = -3, 9
ANSWER
All real numbers greater or equal to -3.
EXPLANATION
The domain of the given function are values of x that make the function defined.
We can see from the graph that, the domain are x-values greater than or equal to -3.
In other words, we can find a corresponding y-value for all x-values greater than or equal to -3.
The correct answer is option D.
(-2x^3 +x -5) * (x^3 -3x)
= x^6*(-2*1) +x^4*(-2*-3 +1*1) +x^3*(-5) +x^2*(-3) +x(-5*-3)
= -2x^6 +7x^4 -5x^3 -3x^2 +15x
