## anonymous 4 years ago Find the domain of f(x)= square root [x+5]-3. Give the answer either in set notation or interval notation

1. anonymous

$\sqrt{a}\ge0$ $x-5\ge0$ $x \ge5$

2. Directrix

Is this f(x)= square root{ [x+5]-3} or f(x)= square root{ [x+5]}-3? Grouping symbols are important for a correct solution.
