Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

doubt
in V3 , general element are of type (a1,a2,a3) , that's why we have taken (a1,a2,a3) . I have taken general element , and you are asking about image element . you can think , which will be more powerful ... So , we always take general element to show onto..
ok
what about the domain? why not (a1,a2,a3)
f(a1,a2,a3)= (a1,a2,aa3) not equal to (a1,a2,a3) . we have let (a1,a2,a3) in codomain , so we want such element in domain , which gives (a1,a2,a3) after applying f .
so acc. to the question we decide the domain and we will always take the general co-domain. right?
yes , all these are 11 class NCERT concepts.. try once their example , that will clear your doubt ..
Thank You, Deepak sir!
