Answer:
Sally ends at 3 feet below zero point.
Step-by-step explanation:
Let be
the height with respect to zero point, which is represented by the following sum:
![h = \Sigma_{i=1}^{n} h_{i}](https://tex.z-dn.net/?f=h%20%3D%20%5CSigma_%7Bi%3D1%7D%5E%7Bn%7D%20h_%7Bi%7D)
Where:
- i-th travelled height, measured in feet.
In addition, positive sign means ascension, whereas negative sign means descent.
The statement can be translated into the following mathematical identity:
![h = h_{1}+h_{2}+h_{3}+h_{4}](https://tex.z-dn.net/?f=h%20%3D%20h_%7B1%7D%2Bh_%7B2%7D%2Bh_%7B3%7D%2Bh_%7B4%7D)
![h = 224\,ft+(-131\,ft)+67\,ft -163\,ft](https://tex.z-dn.net/?f=h%20%3D%20224%5C%2Cft%2B%28-131%5C%2Cft%29%2B67%5C%2Cft%20-163%5C%2Cft)
![h = -3\,ft](https://tex.z-dn.net/?f=h%20%3D%20-3%5C%2Cft)
Sally ends at 3 feet below zero point.
Answer:
C
Step-by-step explanation:
From the table we see that
![f(-2)=12\\ \\f(-1)=10\\ \\f(0)=8\\ \\f(1)=6\\ \\f(2)=4](https://tex.z-dn.net/?f=f%28-2%29%3D12%5C%5C%20%5C%5Cf%28-1%29%3D10%5C%5C%20%5C%5Cf%280%29%3D8%5C%5C%20%5C%5Cf%281%29%3D6%5C%5C%20%5C%5Cf%282%29%3D4)
Thus, the inverse function has the rule
![f^{-1}(12)=-2\\ \\f^{-1}(10)=-1\\ \\f^{-1}(8)=0\\ \\f^{-1}(6)=1\\ \\f^{-1}(4)=2](https://tex.z-dn.net/?f=f%5E%7B-1%7D%2812%29%3D-2%5C%5C%20%5C%5Cf%5E%7B-1%7D%2810%29%3D-1%5C%5C%20%5C%5Cf%5E%7B-1%7D%288%29%3D0%5C%5C%20%5C%5Cf%5E%7B-1%7D%286%29%3D1%5C%5C%20%5C%5Cf%5E%7B-1%7D%284%29%3D2)
This gives us that ordered pairs
![(12,-2),\ (10,-1),\ (8,0),\ (6,1),\ (4,2)](https://tex.z-dn.net/?f=%2812%2C-2%29%2C%5C%20%2810%2C-1%29%2C%5C%20%288%2C0%29%2C%5C%20%286%2C1%29%2C%5C%20%284%2C2%29)
are on the graph of the inverse function
