The domain of this graph is {x | x≥−2}. true. false.

The correct answer is:  [B]:  " True ".

Note:  From visual inspecton of the graph shown — [Note:  all images attached refer to the same graph.] :
 
→  We can see that when "x = -2"  ;  there is only one value for "y" ;  and then the "line" of the graph stops for any coordinate corresponding to any "x-value" LESS THAN "-2" ; 

 →  and that there are corresponding "y-coordinates" corresponding to any "x-value that is equal to "-2" and "GREAT THAN  "-2" .

Idon’t know what the answer is i wish i could
