C) $( - \infty , - 2 )$
D) $[ - 2 , \infty )$

The inequality $- 2 \leq x$ means that x is greater than or equal to -2. In interval notation, we use a square bracket to show that the endpoint is included. Therefore, the correct interval notation for this inequality is $[ - 2 , \infty )$. Choice D is the only option that shows this interval notation.
