Answer:
   D
Step-by-step explanation:
Solve x = f(y) for y.
   x = ∛(y/9) -4
   x +4 = ∛(y/9) . . . . . add 4
   (x +4)³ = y/9 .. . . . . cube
   9(x +4)³ = y . . . . . . multiply by 9
The inverse function is ...
   f⁻¹(x) = 9(x +4)³ . . . . . matches the last choice
 
        
             
        
        
        
49.26 because 90-40.74=49.26
        
                    
             
        
        
        
Answer:
53/10, 5 9/25 ; 5.81 ; 5.818
Step-by-step explanation:
To find the solution we need to make some calculations:  
53/10 = 5.3
5 9/25 = 5.36
So we have that the solution is: 
53/10, 5 9/25 ; 5.81 ; 5.818
