Answer:
- C. The surface area of the pyramid is multiplied by 100
Step-by-step explanation:
The area is the function of the two dimensions.
If each dimension has changed by 10 times, the the area will change by:
Correct choice is C
The inverse of the function is f(x) =
+ 8
In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.
f(x) =
----> Switch f(x) and x
x =
----> Cube both sides
= f(x) - 8 ----> Add 8 to both sides
f(x) =
+ 8
