$\"\"$

The radical function $\"\"$ .

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

Value inside the square root should be greater than or equal to $\"\"$ .

$\"\"$ .

$\"\"$

Consider $\"\"$ .

Solve the equation $\"\"$ .

$\"\"$

$\"\"$ .

Determine the real zeros of $\"\"$ .

The real zero of numerator is $\"\"$ and the real zeros of denominator $\"\"$ .

So the real zeros are divide the $\"\"$ - axis into two intervals.

$\"\"$

The function intervals are $\"\"$ , $\"\"$ , and $\"\"$ .

$\"\"$

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

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