Answer:
<em>g</em><em> has a domain that contains the domain of </em><em>f</em><em> as a subset</em>
Step-by-step explanation:
<u>The Domain of Real Functions</u>
Real functions take values for the independent variable (usually x). The whole set of those values is called the domain of f.
Function f is defined as
It can only exist when the argument is positive, i.e.
Function g is not explicitly defined but we can see its graph. It's evident its domain is
This interval contains the domain obtained for f, so we can conclude g has a domain that contains the domain of f as a subset
