Answer:
Step-by-step explanation:
Let x represent the number of phone call that she routes.
Laylah has already spent 3 minutes on the phone and she expects to spend 1 more minute with every phone call she routes. This means that if she routes x phone calls, the total number of time that Layla would have spent on the phone is
3 + x
If she routes 23 phone calls, the total time that Layla would have spent on the phone in total is
3 + 23 = 26 minutes

Step-by-step explanation:
Property of inverse function:
The function should be bijective function ( one-to-one and onto)
Option A) f(x)=|x-4|+1
It is absolute function. Not one-to-one function.
Domain: All real (-∞,∞)
Range: [1,∞)
False ( Inverse not possible )
Option B) 
It is quadratic function. Not one-to-one function.
Domain: All real (-∞,∞)
Range: [0,∞)
False ( Inverse not possible )
Option C) 
It is polynomial function with even degree. Not one-to-one function.
Domain: All real (-∞,∞)
Range: [0,∞)
False ( Inverse not possible )
Option D) 
It is linear function. one-to-one and onto
Domain: All real (-∞,∞)
Range: All real (-∞,∞)
True ( Inverse possible )
Inverse of
is 
Hence, The function inverse function
is
