for the domain, the answer is all real numbers.
interval notation:(-infinity,+infinity)
for the domain,since it is outside the absolute value sign,it should be positive or zero. then, the domain is all positive real numbers and zero.
interval notation:(0,+infinity)
note:i don't know how to type the infinity sign so i just typed it in words instead.
