Let `f={(1,6),(2,5),(4,3),(5,2),(8-1),(10,-3)}` and `g={(2,0),(3,2),(5,6),(7,10),(8,12),(10,16)}`. Find `(i) dom (f+g) (ii) dom ((f)/(g))`.

Text Solution

Verified by Experts

The correct Answer is:
(i) `{2,5,8,10}` (ii) `{5, 8,10}`
dom `(f+g)="dom "(f)nn"dom "(g)={2,5,8,10}`
dom `((f)/(g))="dom "(f)nn"dom "(g)-[x:g(x)=0}=(2,5,8,10}-{2}={5,8,10}`.
