The radical function $\"\"$ .

Domain is all possible values of $\"\"$ .

Note that a negative value under the square root sign is not possible.

Value inside the square root should be greater than or equal to 0.

Solve the inequality $\"\"$ .

$\"\"$

Consider $\"\"$ .

Solve the equation $\"\"$ .

$\"\"$

$\"\"$ and $\"\"$

$\"\"$ and $\"\"$ .

Solutions of the equation $\"\"$ are $\"\"$ .

$\"\"$

Divide the solutions into three intervals $\"\"$ , $\"\"$ and $\"\"$ .

Now test sample values in each interval to determine whether values in the interval satisfy the inequality.
