The function $\"\"$ .

Rewrite the function as $\"\"$ .

$\"\"$

Interchange x and y.

$\"\"$

Solve for y.

$\"\"$

Replace y by $\"\"$ .

$\"\"$ .

Thus, the inverse function is $\"\"$ . $\"\"$

The function $\"\"$ .

The domain of "f " is the range of " $\"\"$ " is all positive values of x .

Since $\"\"$ is a radical function, radicand should be greater than or equals to zero.
