The function is $\"\"$ .

All possible values of $\"\"$ is domain of the function.

Above function is a radical function.

The expression under the square root (the radicand) must be nonnegative $\"\"$ .

$\"\"$ .

Solve the inequality $\"\"$ .

$\"\"$

Now thee are two ways that this product could be grater than zero both factors are positive or both factors are negative.

If both factors are positive: $\"\"$

$\"\"$

$\"\"$ .

If both factors are negative : $\"\"$

$\"\"$

There are no values for this situation is true.

Solution of the inequality is $\"\"$ .

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

Domain set is $\"\"$ .
