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
