Greetings. 
The range is the set of y-value. 
The range starts from the minimum point to maximum point. 
Our minimum point starts at 0 and maximum point starts less than infinity.
Therefore the range is 0<=y<+inf
However, we do not often write that, although it is right. 
Therefore we write as y≥0
Thus, the answer is B choice.
 
        
             
        
        
        
Soldiers for the nation of Gilead. “Blessed Be the Fruit”: The standard greeting amongst Gilead residents. The traditional reply is “May the Lord open.” “Under His Eye”: The Gileadean equivalent of “Aloha” — it works as both a hello and a goodbye.

The answer is correct because it would have to go like this;
(-4x + 9)² = (-4x + 9)(-4x + 9)
hope this helps, God bless!
