Answer:
a
    No singular point due to the exponent in the solution 
     The interval is   
b
    NONE
Step-by-step explanation:
From the question we are told that 
      
The generally solution is mathematically represented as 
          
=>       
 integrating both sides  
          
   =>   
  =>   
  =>    
Here 
 =>     
From the above equation we see that the domain for x has no singular point the interval is 
        
Also there is no transient term in the general solution obtained because as   there no case where
 there no case where 
 
        
             
        
        
        
No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i.  The Sqrt(11.2) = 3.3466
so the answer is 3.3466i
