Question
Write the inequations that represent the interval and state whether the interval is bounded or unbounded: $(-\infty, 3)$

Answer

$(-\infty, 3)$
Here, $x$ takes values between $-\infty$ and 3
$\therefore$ the required inequation is $-\infty<\mathrm{x}<3$
$\therefore$ it is an unbounded (open) interval.
