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.
