$\"\"$

The function is $\"\"$ .

If the function is $\"\"$ , Domain is $\"\"$ , and the range is $\"\"$ .

The domain only includes values for which the radicand is nonnegative.

$\"\"$ (Write an inequality)

$\"\"$ (Add $\"\"$ to each side)

$\"\"$ (Simplify)

The domain is $\"\"$ . $\"\"$

Find $\"\"$ to determine the lower limit of the range.

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Simplify)

So, the range is $\"\"$ . $\"\"$

The domain of the function is $\"\"$ and range of the function is $\"\"$ .
