The graph of $y=\sqrt{x}$y=x has been translated to the graph of $y=\sqrt{x}-4$y=x4.

A graph of $y=\sqrt{x}$y=x is shown here. By dragging the points provided, plot the curve after it has undergone transformations resulting in the function $y=\sqrt{x}-4$y=x4.

A graph of $y=\sqrt{x}$y=x is shown here.
