Use symmetry to graph the inverse of the function.

The correct option is a.

Step-by-step explanation:

If a function is defined as

then the inverse of the function is

We know that the graph of a function and its inverse function symmetrical about the line y=x.

Draw the line of symmetry x=y in each of the given graph.

From the below figure it is clear that only graph 1 is symmetrical about the line y=x.

Therefore the correct option is a.
