Answer:
A.
Explanation:
Given the function f(x) defined as follows:
![f(x)=-3x^4-x^3+2x^2-5x+12](https://tex.z-dn.net/?f=f%28x%29%3D-3x%5E4-x%5E3%2B2x%5E2-5x%2B12)
The leading coefficient = -3
The degree of the first term = 4
When n(the degree of the first term) is even
![a_n(\text{the leading coefficient) is negative}](https://tex.z-dn.net/?f=a_n%28%5Ctext%7Bthe%20leading%20coefficient%29%20is%20negative%7D)
The graph falls to the left and right, therefore:
![\begin{gathered} \text{Lim f(x) as }x\to-\infty=-\infty \\ \text{Lim f(x) as }x\to\infty=-\infty \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BLim%20f%28x%29%20as%20%7Dx%5Cto-%5Cinfty%3D-%5Cinfty%20%5C%5C%20%5Ctext%7BLim%20f%28x%29%20as%20%7Dx%5Cto%5Cinfty%3D-%5Cinfty%20%5Cend%7Bgathered%7D)
The correct choice is A.

Answer:
$1.98
Step-by-step explanation:
12 ÷ 0.72 = 16.67
33 ÷ X = 16.67
X = 33 ÷ 16.67
=1.98
