can anyone out there please help me ? .. like real fast ?

anonymous · Answer

gof can be defined as : gof(3)=g(5)= 6.... gof (5)=3...gof(6)=3

anonymous · Answer

can you solve it fully .. because i dont understand it at all !.. sorry :/

anonymous · Answer

okk it's easy...gof(3)=g(f(3))...and f(3)=5....gof(3)=g(5)=6...
I hope you will understand !

anonymous · Answer

is that the full answer ?

anonymous · Answer

no ! you can do the others by yourself...gof(5)=g(f(5))...f(5)=...
