Question 73011
<pre>

For the function,        1
                 y =  ______
                       x - 1 

a) Give the y values for x = -2, -1, 0, 1, 2, 3


All you have to do is substitute values of your x to the function to find y.


When x = -2          When x = -1               When x = 0

         1                    1                        1
 y =  ______           y =  ______              y = _______
       x -1                  x -1                    x - 1
 
         1                      1                      1
  =   _______            =  _______               = ________
       -2 -1                -1 - 1                    0 - 1

       1                       1                       1
  = - ____              =  - _____                =  _____  0r  -1
       3                       2                       -1





When x = 1                   When x = 2           When x = 3

       1                          1                      1
y = _______                 y = _______           y = _______
     x - 1                       x - 1                 x - 1


       1                          1                      1
  =  _____                    = _______             = _______
     1 - 1                      2 - 1                  3 - 1 
 
       1                         1                       1
  = _______ or undefined      = ___  or 1           =  ______
       0                         1                       2


     x      -2     -1       0       1        2          3

     y    -1/3    -1/2     -1   undefined    1         1/2


  
b) Using these points, draw a curve.

To graph, plot the points  (-2, -1/3), (-1, -1/2), (0, -1), (1, undefined)
(2, 1) and (3, 1/2). Draw the curve

The graph looks like this


{{{graph (300, 300, -3, 5, -4, 7, 1/(x-1))}}}
