1. The problem is to graph the function $$y=\sqrt{x}+4$$. 2. The square root function $$y=\sqrt{x}$$ starts at the origin (0,0) and increases slowly to the right. 3. Adding 4 to the function shifts the entire graph vertically upward by 4 units. 4. So the graph of $$y=\sqrt{x}+4$$ starts at point (0,4) and rises to the right. 5. Among the options, the graph that starts at (0,4) and rises rightward is option D. 6. Therefore, the correct graph is D.
