Answer:
The correct option is d.
Step-by-step explanation:
Let a function is f(x) and its inverse is f⁻¹(x). If both functions drawn on a coordinate plate than the graph of f(x) and f⁻¹(x) are mirror image of each other across the line y=x.
In other word the line y=x is the axis of symmetry of the graph of function and its inverse.
We need to find the correct graph that represent the function and its inverse.
Draw a line y=x in each graph as shown below.
From the below graph it is clear that only graph d represent the function and its inverse because both the functions are mirror image of each other across the line y=x.
Therefore the correct option is d.
