Question 77193
For the equation x-2sqrtx=0 , perform the following:
a) Solve for all values of x that satisfies the equation.
Answer: 
Show work in this space.
2sqrtx=x
Square both sides after dividing both sides by 2 to get:
x=(x/2)^2
x=x^2/4
x^2-4x=0
x(x-4)=0
x=0 or x=4
============

b) Graph the functions y = x and on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs.
Graph:

Points of intersection: 
You did not post both of the functions.
The one you did post is a line thru (0,0), (1,1)
