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
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
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
