Answer: 
Step-by-step explanation:
To find the inverse of a function replace f(x) with x and the original x with y
Now we can solve for y
Square both sides so we can cancel out the root
Now subtract 7 from both sides
Now replace y with the inverse of f(x), 
You know the answer is the third choice (C) because 7^2 is 49 and 8^2 is 56, the two closest squared numbers to 54.
49 < 54 < 56
The square root of 54 is roughly 7.4
I hope that helps :)
