    Hmm this is a weird function. Here is what it looks like graphed. https://www.desmos.com/calculator/iqh4upoyle We need the points of intersection. Were you able to find those yet?

    The issue I'm having with this problem is finding the exact intersection of the two lines.

    So we set the two functions equal to one another, Then solve for x.\[\large y=x \qquad \qquad \qquad y=2x\sqrt{1-x^2}\] \[\large x=2x\sqrt{1-x^2}\]Solve for x! :D
