D, because of the arrows going both directions, you know part of it,
![( - \infty \: x) \: ( x \: \infty )](https://tex.z-dn.net/?f=%28%20-%20%20%5Cinfty%20%5C%3A%20%20x%29%20%5C%3A%20%28%20x%20%20%5C%3A%20%20%5Cinfty%20%29)
and then you just have to put in the values from the number line. The first arrow ends at zero with a bracket, and brackets mean the number is included. So now you have,
( - infinity, 0] ( x, infinity)
Then, your last value is at 1/2 with a parentheses, indicating it is not included. So, your final answer would be,
( - infinity, 0] ( 1/2 , infinity)
{infinity is always written with a parentheses in domain}
