Answer
The range is $n(x)\geq 0$.
The graph is shown below.
Work Step by Step
The given function is
$n(x)=5\sqrt{x}$
Use the domain of $n$, $x\geq 0$, to make a table of values.
Plot the ordered pairs.
Draw a smooth curve through the points, starting at $(0,0)$.
From the graph, the range of $g$ is $n(x)\geq 0$.
The range is $n(x)\geq 0$.
The graph is shown below.
