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 
14/2 is equivalent to 7/1
Answer: 6.19
Step-by-step explanation: 106.25 divided by 17 is around 6.19.
