Answer:
(-1, 19) and (3, -81)
Step-by-step explanation:
f(x) = 2x³ − 6x² − 27x
f'(x) = 6x² − 12x − 27
-9 = 6x² − 12x − 27
0 = 6x² − 12x − 18
0 = x² − 2x − 3
0 = (x + 1) (x − 3)
x = -1 or 3
f(-1) = 19
f(3) = -81
The points are (-1, 19) and (3, -81).

Step-by-step explanation:
Option (A) represents the function and its inverse of a function option (A) is correct.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function and inverse of a function shown in the picture.
Checking for option (A):
![\rm f(x) = \dfrac{x}{4}+10 \ \ \ and \ \ \ g(x) = 4x -10](https://tex.z-dn.net/?f=%5Crm%20f%28x%29%20%3D%20%5Cdfrac%7Bx%7D%7B4%7D%2B10%20%5C%20%5C%20%5C%20and%20%5C%20%20%5C%20%5C%20g%28x%29%20%20%3D%204x%20-10)
Taking f(x):
![\rm f(x) = \dfrac{x}{4}+10](https://tex.z-dn.net/?f=%5Crm%20f%28x%29%20%3D%20%5Cdfrac%7Bx%7D%7B4%7D%2B10)
To find the inverse of a function interchange the x and y variables:
f(x) → x
x → g(x)
![\rm x = \dfrac{g(x)}{4}+10](https://tex.z-dn.net/?f=%5Crm%20x%20%3D%20%5Cdfrac%7Bg%28x%29%7D%7B4%7D%2B10)
Solving:
4x = g(x) + 10
g(x) = 4x - 10
Similarly, we can find the inverse of a function.
Thus, option (A) represents the function and its inverse of a function option (A) is correct.

I'm not sure which you mean, so I'll give the answer to both:
![70 X 10^2 = 7000\\(70x10)^2 = 490000](https://tex.z-dn.net/?f=70%20X%2010%5E2%20%3D%207000%5C%5C%2870x10%29%5E2%20%3D%20490000)
