  Draw the graphs of the functions y = x and y = 1/x on the same diagram for -5</= x </5

   

  State the coordinates of the intersecting points of the 2 graphs. Answer's (-1,-1) and (1,1). Can someone briefly draw out how the graph looks like and the line y=x?

   

   

  thanks!

  i'm plotting from 0<x<2 for you to have an idea first...

  you must know how to draw y=x and y=1/x. they are one of the most basic graphs!

  Eh, yea I do know how to draw them separately. I just am not sure what the question is asking for.

  May I know how you get a straight line for y=x? and how do you get the plotting points for y=x?

  Dont be a troll k?

  y=x means for eg 10=10, 5=5, 2.5=2.5, -1=-1, -100000=-100000, 0=0

  i wonder how u really meant what you said, when you say you can draw y=x and y=1/x seperately.
  
  do you know what are straight line graphs of the family y=mx+c?
