$\text{Domain: all real numbers} \\\text{Range: } \{20\}$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$ To find the domain and range of the given function, $g(x)=20 ,$ use the concepts of the constant function. $\bf{\text{Solution Details:}}$ The constant function, $g(x)=20 ,$ is a horizontal line that passes through $(0,20).$ Hence, it has the following characteristics: \begin{array}{l}\require{cancel} \text{Domain: all real numbers} \\\text{Range: } \{20\} .\end{array}
