Graph the Linear Function and Give the Domain and the Range

Graph the linear function and give the domain and the range. If the function is a constant function, identify it as such.
- $$\mathrm { h } ( \mathrm { x } ) = 5$$

A) $D = \{ 5 \} , R = ( - \infty , \infty )$
$\text { constant function }$


B) $D = \{ 5 \} , R = ( - \infty , \infty )$
constant function

C) $D = ( - \infty , \infty ) , R = \{ 5 \}$
constant function


D) $D = ( - \infty , \infty ) , R = \{ 5 \}$
constant function
