Consider the parrent function [tex]y=\sqrt{x}.[/tex] The graph of this function you can see in the attached diagram (red line).
1. Reflect this graph about the x-axis, then the function becomes [tex]y=-\sqrt{x}[/tex] (blue line).
2. Translate the reflected graph 2 units up, then the function becomes [tex]y=-\sqrt{x} +2[/tex] (green line).
Answer: correct choice is B.
