Answer
See graph
Work Step by Step
Finding the domain of the function:
$$4-x\geq0$$ $$-x\geq-4$$ $$-x(-1)\leq-4(-1)$$ $$x\leq 4$$
At $x=4$:
$$y=\sqrt{4-4}=0$$
Thus, a point is at $(4,0)$.
Similarly, as based on the domain, other two points can be found at $(-5,3)$ and $(0,2)$.
Plotting the three points and drawing a curve passing them, the sketch of the graph is as shown.
