The values produced by the function

will not be any lower than -7, but may be that low when x=-3.
That is, the range is
... f(x) ≥ -7 . . . . matches the 1st selection
 
        
                    
             
        
        
        
Answer:
523.6
Step-by-step explanation:
Here is the equation to get that answer: 
V=4/3πr3=4/3·π·53≈523.59878
 
        
             
        
        
        
The correct answer is C. 
Because by looking at the diagram you can see that angles 7 and 8 are intersected
 
        
             
        
        
        
This is the quadratic formula
 
        
        
        
The answer would be 92 for this problem
