Question

Represent in Interval notation

Answer 1

Answer:  $[5, \infty)$

On a keyboard, you would write [5, infinity)

The square bracket means "include this value" and a curved parenthesis means "exclude this value". We cannot include infinity as it is not a number, so we always use parenthesis with either infinity.

$y \ge 5$ is the same as $5 \le y$ which is also the same as $5 \le y < \infty$ which may help lead to set up the interval notation answer.
