Answer:
B) x<= 0
Step-by-step explanation:
of you look at the graph, the line stops at the coordinates (0, 9)
the x coordinate here is 0. so x<0.
since it's a closed circle around where the line ends, the domain becomes
x <=0
the rest of the line goes on for infinity, so that's all of the equation.
sorry if the explanation is hard to understand.
