1/2 STO "x,t,Q-key" ENTER
(x-VAR-2)/("x,t,Q-key"("x,t,Q-key"-1)) ENTER
The given expression evaluated for x=1/2 is 6.
-2 STO "x,t,Q-key" ENTER
Recall the expression:
ENTRY ENTRY
ENTER
The given expression evaluated for x=-2 is -2/3.
of x
for various values of x = 1/2, -2
| Assign a value for x:
1/2 STO "x,t,Q-key" ENTER |
|
| Enter your expression:
(x-VAR-2)/("x,t,Q-key"("x,t,Q-key"-1)) ENTER The given expression evaluated for x=1/2 is 6. |
|
| Assign a new value for x:
-2 STO "x,t,Q-key" ENTER Recall the expression: ENTRY ENTRY |
|
| Evaluate it for the new value of x:
ENTER The given expression evaluated for x=-2 is -2/3. |
|
| Repeat the previous two steps additional values
of x |
for various values of x = 1/2, -2
| Press TABLE |  |
| Select TBLST (Table Setup) by pressing F2 |  |
| Use the arrow keys to select "Indpnt Ask" (so you can subsequently specify the values of the independent variable x), and ENTER |  |
| Press GRAPH, select y(x)=
and define the function
y1 = (x-2)/(x*(x-1)) |
For more info, see "Graphing" |
| Press TABLE, select TABLE,
enter 1/2, ENTER
you now see function y1 evaluated for x=1/2 (it's 6) |
 |
| enter -2, ENTER, see this: |  |
| continue by entering as many values as you wish
you may "write over" any entry by using the "up arrow" |
