Answer
The possible function corresponding to the graph is $y=\sqrt{x-2}$.
Work Step by Step
The above shown graph is similar to the graph of the function $y=\sqrt{x}$ but the graph of the function $y=\sqrt{x}$ passes through the origin.
The above given graph starts from the point $x=2$. Thus, the graph shifs horizontally right by 2 units.
Thus, the graph is shifted by c units so, the function is of the form $y=\sqrt{x-c}$ , where the value of $c$ is 2.
Therefore, the possible function is $y=\sqrt{x-2}$.
