Bounded Subset of Real Numbers/Examples/Example 2

Example of Bounded Subset of Real Numbers
The subset $T$ of the real numbers $\R$ defined as:
 * $T = \set {x \in \R: 1 \le x \le 2}$

is bounded both above and below.

Some upper bounds of $T$ are:
 * $100, 10, 4, 2$

Some lower bounds of $T$ are:
 * $-27, 0, 1$
