Graph A

Work Step by Step

The x intercept of the graph of y =$\sqrt x$ is (0,0) as shown below in the graph. The equation y =$\sqrt (x-2)$ has the d value of 2 which means that the graph is moved to the right two units. This means that the new x intercept of the graph is (2,0). The x intercept of the graph A is (2,0). Thus the equation matches graph A.
