Answer
Solution set includes all numbers greater than or equal to -2 and less than or equal to 0. In interval notation $[-2,0]$
Work Step by Step
$x \leq 0$ all numbers less than or equal to zero for $x$.
$x \geq -2 $ all numbers greater than or equal to -2 for $x$.
Solution set for $x \leq 0$ and $x \geq -2 $ are all numbers greater than or equal to -2 and less than or equal to zero.
Solution set in interval notation: $[-2,0]$
