RATL 3 | Lesson 2 | Solutions (Solution Sets)

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?
