Question 57222
Please can one of you guys help me with this problem? 
Graph the function y=x and {{{y=2*sqrt(x)}}} 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(300,200,-10,10,-10,10,x)}}}
for {{{y=2*sqrt(x)}}}
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(300,200,-10,10,-10,10,x,2*sqrt(x))}}}
The graphs intersect: (0,0) and (4,4)
Happy Calculating!!!
