Here are the graphs:
graph%28300%2C200%2C-5%2C5%2C-2%2C5%2Cx%2C2sqrt%28x%29%29
From the graph, the points of intersection are (4, 4) and (0, 0)

Graph the function y=x and y=2%2Asqrt%28x%29 on the same graph.
Show the points of intersection of these two graphs.
Plot the line:
x=y
let x=0 and y=0, plot (0,0)
let x=1 and y=1, plot (1,1)
Connect the points and you have:
graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Cx%29
for y=2%2Asqrt%28x%29
let x=0 and y=0
let x=1 and y=2(1)=2
let x=4 and y-2*2=4
Coonect the dots and you have a curve to go with your line:
graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Cx%2C2%2Asqrt%28x%29%29
The graphs intersect: (0,0) and (4,4)
Happy Calculating!!!
