We actually don't need to do any computation. By definition, the inverse function
changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.
You have to think like this: if the function makes a step further, the inverse function makes that same step back.
This means that the composition
is always the identity function
. In fact,

So, for every function, you have

Answer:
A
Step-by-step explanation:
Subtract 1 from both sides and divide by 2. This will leave you with x=-2 which is the simplified form of the equation.
