The graph is shown below:

Work Step by Step

The graph of y =$\sqrt x$ is shown below. To get the graph y =$ 2 \sqrt (x-3) $ we see that the a value is 2. So we multiply the y value of each point by 2 to get the final graph, because we multiply the y by the a value. There is also a d value of 3, which shifts the graph horizontally. So we move the graph of y =$\sqrt x$ to the right 3 units by adding 3 to each x value.
