Question 52261
Evaluate:
{{{y = 1/(x-1)}}} for:
x = -2, -1, 0, 1, 2, 3

What you do here is replace the x with the x-values above, one-by-one, and find the corresponding values of y.
For x = -2:
{{{y = 1/(-2-1)}}}
{{{y = 1/(-3)}}}
{{{y = -1/3}}}

For x = -1:
{{{y = 1/(-1-1)}}}
{{{y = 1/(-2)}}}
{{{y = -1/2}}}

For x = 0:
{{{y = 1/(0-1)}}}
{{{y = 1/-1}}}
{{{y = -1}}}

Foe x = 1:
{{{y = 1/(1-1)}}}
{{{y = 1/0}}} Undefined! Division by zero is a prohibited mathematical operation!

For x = 2:
{{{y = 1/(2-1)}}}
{{{y = 1/1}}} {{{y = 1}}}

For x = 3:
{{{y = 1/(3-1)}}}
{{{y = 1/2}}}

Do you see the idea here?
Now you can place the x-values and their corresponding y-values in their appropriate places in the table.
