Answer:
A
Step-by-step explanation:
The parabola ends at 4, and therefore the range is all real numbers under 4
 
        
             
        
        
        
Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8
The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign. 
After doing this, we realize that only -1 works, so the answer is x=-1
Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:) 
Best wishes:)
        
             
        
        
        
Answer: You take the last two digits of the original number and see if they are divisible by 4.
