The function is $\"\"$ .

All possible values of $\"\"$ is the 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: $\"\"$

$\"\"$

The only condition that makes both true is $\"\"$ .

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

$\"\"$

The only condition that makes both true is $\"\"$ .

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

The domain of the function is in interval notation: $\"\"$ .

Domain set is $\"\"$ .
