Question 83303
For the equation x – radical sign and the radicand under it of x = 0, perform the following: 
Solve for all values of x that satisfies the equation.
EQUATION:
x-sqrt(x) = 0
x=sqrt(x)
Square both sides to get:
x^2=x
x^2-x=0
x(x-1)=0
x=0 or x=1
------------------ 
Graph the functions y = x and y = radical sign and the radicand under it of x on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs. 
Graph 
{{{graph(400,300,-5,3,-5,3,x,sqrt(x))}}}
Points of intersectin: (0,0), (1,1)
------------------------------
How does the graph relate to part a?
It confirms the results of part a.
