Finding the inverse function:
We are given a function y = f(x). To find the inverse function, we exchange x with y in the original function, and then isolate y.
So
We are given the function:
So
Changing x with y
Now, we have to isolate y. So
We can apply the fifth root to both sides. So:
![\sqrt[5]{(y+7)^5}=\sqrt[5]{x}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%28y%2B7%29%5E5%7D%3D%5Csqrt%5B5%5D%7Bx%7D)
![y+7=\sqrt[5]{x}](https://tex.z-dn.net/?f=y%2B7%3D%5Csqrt%5B5%5D%7Bx%7D)
![f^{-1}(x)=y=\sqrt[5]{x}-7](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3Dy%3D%5Csqrt%5B5%5D%7Bx%7D-7)
DOMAIN:
- Set of allowable inputs (set of 1st elements of the ordered pairs in relation)
- X point
- AKA the input
DEFINE INPUT:
A number that'll be used in a function rule to determine the value of the output
RANGE:
- Set of possible outputs (set of 2nd elements of the ordered pairs in relation)
- Y point
- AKA the output
DEFINE OUTPUT:
Result of applying a function rule to the value of ani input
ORDERED PAIRS:
(-1, 7): -1 is the domain & 7 is the range
(3, 5): 3 is the domain & 5 is the range
(4, 9): 4 is the domain & 9 is the range
(-6, -10): -6 is the domain & -10 is the range
(-2, 8): -2 is the domain & 8 is the range
Hope this helps you!!! :)
I believe the answer would be X=7

Answer:
See below.
Step-by-step explanation:
Total = 110
Let calls on third evening = x
second evening = 4x
first evening = x + 8
=> x + 4x + x + 8 = 110
=> 6x = 102
=> x = 17
First evening = x = 17 calls
Second evening = 4x = 68 calls
Third evening = x + 8 = 25 calls
