Answer 1

Domain: The set of all possible input values (commonly the "x" variable) It is the set of all real numbers for which a function is mathematically defined.  

$f(x) = \sqrt[1]{x-9}$ 

The function has noun defined points nor domain constraints. Therefore, the domain is 

$- \infty} \ \textless \ x \ \textless \ \infty}$
