Graph B

#### Work Step by Step

The y 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 c value of 4 which means that the graph is moved up four units. This means that the new y intercept of the graph is (4,0). The y intercept of the graph B is (4,0). Thus the equation matches graph B.
