Step-by-step explanation:
The question has conflicting details
and three halves doesn't sound correct.
So, I will take f(x) as
Next, solve for the inverse function
Replace f(x) with y
Swap x and y
Make 2y the subject
Make y the subject
Replace y with the inverse sign
So, now we can calculate any value from the original function and from the inverse function.
For instance:
