Use the Select Radical slider to compare the graphs of $$\sqrt { x } , \sqrt[ 4 ] { x } , \sqrt[ 6 ] { x } , \sqrt[ 8 ] { x } \ldots$$ What is the domain of these radical functions? Use the interactive figure to find your answer. Use the left and right arrow keys to move along a slider as needed. The domain is $$\square$$ . (Type your answer in interval notation.)
$$[0,\infty )$$
