🔶05 - Point Set, Intervals and Absolute Value Equations and Inequalities

In todays video, we shall look at the point set, interval notations and absolute value equations and inequalities.

A real number corresponds to exactly one point on the number line and a point on the number line also corresponds to only one real number.
A set of points (real numbers) located on the real number line or axis is called a one dimensional point set.

An interval is the set of real numbers found between two real numbers
Types of Intervals:
Open Interval
Closed Interval
Half open / half closed Interval

Bounded Intervals
