Answer:
See explanation
Step-by-step explanation:
You are given the function 
The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:

The table is

The inverse function
has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}
If this is what you have in mind
(1/2)x + 5 = 9
Then solving this is quite simple
1st subtract 5 from both sides
(1/2)x = 4
Now divide 1/2 by both sides
x = 8
