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.
