Question 56676: For the equation x-2sqrx=0 , perform the following:
a) Solve for all values of x that satisfies the equation.
Answer:
Show work in this space.
b) Graph the functions y = x and y=2sqrx on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs.
Graph:
Points of intersection:

You can put this solution on YOUR website! For the equation  , perform the following:
a) Solve for all values of x that satisfies the equation.
Answer: x={0,4}
Show work in this space.
 and  -->
Check for extraneous solutions:
 x=0 checks.
x=4 checks also.
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: (0,0) and (4,4)
For y=x
Let x=0, solve for y
y=0, plot (0,0)
Let x=4, solve for y
y=4, plot (4,4)
Connect the dots and you have a line.
For 
Let x=0
y=0, Plot (0,0)
Let x=1
 , plot (1,2)
Let x=4
y=4, plot (4,4)
Connect the dots and you have a curve.
Their points of intersections are (0,0) and (4,4)
Happy Calculating!!!!
