Worked example
Create a table for f(x)=x²−4 from x=−3 to x=3.
x^2 - 4
- Open the Table tab.
- Enter
x^2-4as the function. - Set Start to −3, End to 3 and Step to 1.
- Choose Create table.
| x | x²−4 |
|---|---|
| −3 | 5 |
| −2 | 0 |
| −1 | −3 |
| 0 | −4 |
| 1 | −3 |
| 2 | 0 |
| 3 | 5 |
Choose a useful step
A step of 1 is common for integer tables. Use 0.5 or 0.1 when the behavior between integers matters, but avoid producing hundreds of rows unnecessarily.
Undefined values
A function such as 1/x is undefined at x=0. The table marks that row as undefined rather than stopping the whole calculation.
Practice
Create a table for 2x+3 from −2 to 2.
Show values
The y-values are −1, 1, 3, 5 and 7.
