Let `f:{2,3,4,5} rarr {3,4,5,9}` and `g:{3,4,5,9} rarr{7,11 , 15}` be functions defined as `f(2)=3`,` f(3) =4`, `f(4)=f(5)=5` and `g(3)=g(4)=7` and `g(5)=g(9)=11` . Find `gof`.

Text Solution

Verified by Experts

We have .g o f(2)=g f((2))=g(3)=7, gof(3)=g(f(3))=. g(4)=7, gof(4)=g(f(4))=g(5)=1 T. and gof .(5)=g(5)=11.
