What exactly do you mean by *? Like exponent? If so the domain is R= −∞,∞ with its range being [−1,1]. If this wasn’t meant by exponent, please comment and I’ll reply ASAP!
Surface area of sphere is 
Step-by-step explanation:
We need to find the surface area of the sphere while we are given volume of sphere = 972π
The formula used to find surface area is:
We need to find radius of sphere
We are given Volume = 972π, using this volume we can find radius of sphere
The formula used to find volume is:
Putting values and finding r
Taking cube root on both sides
![\sqrt[3]{r^3}=\sqrt[3]{729}\\ r=9](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%3D%5Csqrt%5B3%5D%7B729%7D%5C%5C%20r%3D9)
So, Radius of sphere r=9
Now finding surface area:
So, surface area of sphere is

Answer: Choice B
(x-1)(x^3+x^2+5x+6)
==========================================
Explanation:
The 1 in the upper left box means that x = 1 is a root of the original polynomial.
So this means x-1 is a factor of the original polynomial.
This is because x = 1 leads to x-1 = 0 after subtracting 1 from both sides.
-----------------
The 0 in the last position of the bottom row shows we got a remainder of 0.
Getting a remainder 0 tells us that (x-1) is a factor of the polynomial. This synthetic division table confirms our initial guess.
The other values in that bottom row (1, 1, 5, 6) form coefficients to the polynomial 1x^3+1x^2+5x+6, or simply x^3+x^2+5x+6
-------------------
So we know that (x-1) and (x^3+x^2+5x+6) are factors
Meaning that,
x^4+4x^2+x-6 = (x-1)(x^3+x^2+5x+6)
You can confirm this by expanding out the right hand side (distribution rule).
