Answer by xcentaur(357) (Show Source):
You can put this solution on YOUR website!
Put values of x=0,-1,1,-2,2,and so on for both functions. Plot the corresponding results.
Your graph should look like this:

You can see the point of intersection of these graphs clearly.
To solve this using algaebra,
y=x....[1]
y=sqrt(x)....[2]
solve the two simueltanously,

This implies
sqrt(x)=0 and (sqrt(x)-1)=0
sqrt(x)=0 and sqrt(x)=1
so the only places where this condition for the number and its root to be the same will be fulfilled will be at 0 and 1

Hope this helps,
