Domain of f is D1 and g is D2. Then domain of f+g is

(a)D1/D2 (b) D1-(D1/D2) (C)D2 /(D2/D1) (D) D1 ∩ D2

More than one correct. Explain how?

Hi Aditi,

 

For the sum to be defined, both the functions should be defined in the Domain.

 

Which will be possible only when Domain is D1∩D2.

Option (D).

 

Hope that helps.

 

Best Regards,

Ashwin (IIT Madras).
