D, because of the arrows going both directions, you know part of it,
( -  \infty \:  x) \: ( x  \:  \infty )
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}
