$\"\"$

Observe the graph :

The function $\"\"$ is a one-to-one function.

Let us consider points on the graph of $\"\"$ .

Points are $\"\"$ , $\"\"$ and $\"\"$ .

Domain of the function $\"\"$ is $\"\"$ .

Range of the function $\"\"$ is $\"\"$ .

If the function is one-to-one, then range of inverse function is domain of the function and domain of inverse function is range of the function.

Domain of the inverse function $\"\"$ is $\"\"$ .

Range of the inverse function $\"\"$ is $\"\"$ .

The points are $\"\"$ , $\"\"$ , $\"\"$ .

Graph :

Graph the inverse function $\"\"$ .

Draw the coordinate plane.

Plot the points of $\"\"$ and $\"\"$ .

Connect the points using the smooth line.
