Answer
$[-8, +\infty)$
Work Step by Step
The interval begins at, and includes $-8$. This means that a bracket will be used on the left part of the interval notation.
The interval goes all the way to the right without bound so the interval goes to infinity. This means that a parenthesis will be used on the right end of the interval.
Therefore the interval notation of the given interval is
$[-8, +\infty)$.
