$\"\"$

Horizontal line test:

A function $\"\"$ has an inverse $\"\"$ if and only if no horizontal line intersects its graph of the function in at most one point.

The function $\"\"$ is a one-to-one function.Therefore the inverse of the function does exist.

Let us consider table of $\"\"$ and $\"\"$ .

Observe the Table.

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 table of inverse function $\"\"$ .
