Answer:
Inverse does not exist.
Explanation:
Given is a function
We are asked to find an inverse for this function.
On analysing the function, we find that for all values of x,
y is a constant.
In other words, this is nothing but a constant function which is a horizontal line parallel to x axis.
This is not onto, because range of this funciton is only the value {3^3}
Inverse exists only for one to one and onto funcitons.
Since this function is one to one but not onto, inverse does not exist.
