Answer:
c. 500 + 24 * 8
Step-by-step explanation:
if there is 500 gallons of water already in the swimming pool and we are trying to add more and we are adding 24 gallons for 8 minutes to the already existing pool of water.
Your answer is yes because 2 rounds to 0 so the hundredths place stays the same. <u><em>So your answer is 1.68</em></u>

Answer:
![{f}^{ - 1} (x) = \frac{{4}^{x} }{3}](https://tex.z-dn.net/?f=%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7B%7B4%7D%5E%7Bx%7D%20%7D%7B3%7D%20)
Step-by-step explanation:
The given logarithmic function is
![f(x) = log_{4}(3x)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20log_%7B4%7D%283x%29%20)
Let y=f(x)
This gives us:
![y = log_{4}(3x)](https://tex.z-dn.net/?f=y%20%3D%20%20log_%7B4%7D%283x%29%20)
We interchange x and y to get:
![x = log_{4}(3y)](https://tex.z-dn.net/?f=x%20%3D%20%20log_%7B4%7D%283y%29%20)
![{4}^{x} = 3y](https://tex.z-dn.net/?f=%20%7B4%7D%5E%7Bx%7D%20%3D%20%203y)
![y = \frac{{4}^{x} }{3}](https://tex.z-dn.net/?f=y%20%3D%20%20%20%5Cfrac%7B%7B4%7D%5E%7Bx%7D%20%7D%7B3%7D%20)
Therefore the inverse is
![{f}^{ - 1} (x) = \frac{{4}^{x} }{3}](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7B%7B4%7D%5E%7Bx%7D%20%7D%7B3%7D%20)
Based on the possible answers, B is most closed to the inverse.
The correct answer is B
