Answer:
Option: D is the correct answer.
Step-by-step explanation:
We are given a function g(x) such that the mapping is as follows:
1-->3
2-->6
3-->9
4-->12
We know that for any function g(x) the inverse function of this function is nothing but the interchange of the range and domain of the original function.
i.e. the x and y value of the function get swapped.
Hence, the mapping of inverse function will be done as follows:
3 ------> 1
6 ------> 2
9 -------> 3
12 ------> 4
