opcode · Answer

$\sqrt{3 -x}~\ge~0$ domain is not to be imaginary, solve the inequalities for the top and bottom. So no, that interval notation is incorrect.

opcode · Answer

Variables are not mutable, once assigned a value they will not change you must construct an interval notation that pleases both the top and bottom inequalities.

opcode · Answer

Drop what is after the union symbol. Remember you want $x$ to be able to satisfy the top.
