Answer
The correct graph is $B$.
From the graph, the range of $y$ is $y\geq 0 $
Work Step by Step
The given function is
$y=\sqrt{-x+3}$
Use the domain of $y,x\leq 3,$ to make a table of values.
Plot the ordered pairs.
Draw a smooth curve through the points, starting at $(3,0)$.
Hence, the correct graph is $B$.
From the graph, the range of $y$ is $y\geq 0 $
