Question

Two functions are represented below. Which function has a domain that contains the domain of the other as a

Answer 1

Answer:

g has a domain that contains the domain of f as a subset

Step-by-step explanation:

The Domain of Real Functions

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

$f(x)=-log(x+3)-2$

It can only exist when the argument is positive, i.e.

$x+3>0$

$x>-3, (-3,\infty)$

Function g is not explicitly defined but we can see its graph. It's evident its domain is

$(-5,\infty)$

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
