$\"\"$

\

Observe the graph :

\

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

\

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

\

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

\

Observe the graph.

\

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 :

\

Draw the coordinate plane.

\

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

\

Connect the points using a smooth curve.

\

Observe the graph :

\

The inverse function is the reflection of the function about the line $\"\"$ .

\

\

Graph of the inverse function $\"\"$ :
