From the problems on the previous page, here is the completed chart.
| Problem | Basic Style | Set Builder | Interval |
|---|---|---|---|
| a | \(-3≤ x <2\) | \({x|-3≤ x <2}\) | \([-3, 2)\) |
| b | \(-2< x< 3\) | \({x|-2< x < 3}\) | \((-2, 3)\) |
| c | \(-3 < x ≤ 1\) | \({x|-3 < x ≤ 1}\) | \((-3, 1]\) |
| d | \(-1 ≤ x ≤ 3\) | \({x|-1 ≤ x ≤ 3}\) | \([-1, 3]\) |
To help remember, think about what the different notations share in common and what is different about them. Which notations do you feel most comfortable and why?
