Graph D

The x intercept of the graph of y =$\sqrt x$ is (0,0) as shown below in the graph. The equation y =$\sqrt (x+4)$ has the d value of -4 which means that the graph is moved to the left four units. This means that the new x intercept of the graph is (-4,0). The x intercept of the graph D is (-4,0). Thus the equation matches graph D.
