$y$ $y$ is the standard graph of $\sqrt{x}$ $sqrtx$ scaled by 2.

The graphs below show the standard $\sqrt{x}$ $sqrtx$ (lower) and the graph of $y$ $y$ being $\sqrt{x}$ $sqrtx$ scaled by 2.

graph{(y-2sqrtx)*(y-sqrtx)=0 [-1, 5, -1, 5]}

How do you graph y=2√xy=2sqrtx and compare it to the parent graph?
