For the function,        1

                 y =  ______

                       x -1 



give the values for x = -2,-1, 0,1,2,3 where do I begin?  Is there a formula?





Are you going to find values of y? if so, 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

       -2 -1                -1 - 1                    0 - 1

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

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





  



To graph, plot the points  (-2, -1/3), (-1, -1/2), (0, -1), (1, undefined)

(2, 1) and (3, 1/2)



The graph looks like this
