Answer:
option (b) is correct
inverse of function
is 4x+3
Step-by-step explanation:
Given function 
We have to find the inverse of given function.
Let f(x) = y then taking inverse both sides, we get

Substitute , x and f(x) in given equation, we get,

Now solve for
, we get,


Thus, inverse of function
is 4x+3
Thus, option (b) is correct.
