Question 58635: okay ineed help graphing tese functions y=x and y=2sqrt of x it says to plott points if neccesary and show points of intersection of thses two graphs i dont think i did it right cause i dont have any points of intersection can someone show me what i am doing wrong give me an example please

You can put this solution on YOUR website! Graph y=x and  Plot points if neccesary and show points of intersection of thses two graphs.
For y=x
if x=0, then y=0. Plot (0,0)
if x=4, then y=4 Plot (4,4) Since this is a line, connect the points and you have a line.
For
If x=0, then  Plot (0,0)
If x=1, then  Plot (1,2)
If x=4, then  Plot (4,4)
If x=9, then  Plot (9,6)
Notice that they share the points (0,0) and (4,4). I picked those points on purpose because I found their points of intersections algebraically this way:
x=0 and x-4=0
x=0 and x=4
Don't worry about that if you haven't gotten that far yet.
Here's the graphs together, you can see their points of intersection is (0,0) and (4,4):
Happy Calculating!!!
