Final answer:
To find the inverse of a function represented by a mapping diagram, swap the input and output values.
Step-by-step explanation:
To find the inverse of a function represented by a mapping diagram, we need to swap the input and output values. In other words, if the original mapping shows pairs of values (x, y), the inverse mapping will show pairs of values (y, x).
In the given mapping diagram, if S(x) is the original function, the inverse function will be shown in the mapping diagram where the inputs and outputs are swapped.
Answer: The mapping diagram that shows the inverse of S(x) is the one where the inputs and outputs are swapped.
