Answer
a) $g(10)=7$
b) $\text{Domain: all real numbers}
\\\text{Range: }
\{7\}
$
Work Step by Step
a) For any $x,$ the value of the constant function, $g(x)=7,$ is $7.$ Hence, $
g(10)=7
.$
b) The constant function, $f(x)=c,$ has the set of all real numbers as its domain, and its range as $\{c\}.$ Hence, the given function has the following characteristics:
\begin{array}{l}\require{cancel}
\text{Domain: all real numbers}
\\\text{Range: }
\{7\}
.\end{array}
