Let `f:{2,3,4,5}vec{3,4,5,9}a n dg:{3,4,5,9}vec{7, 11 , 15}` be functions defined at `f(2)=3,f(3)=4,f(4)=f(5)=5,g(3)=g(4)=7,a n dg(5)=g(9)=11. F in dgofdot`

Text Solution

Verified by Experts

As, range of f is subset of domain of g
Therefore , gof is well defined.
Domain `(gof)`= Domain f
`={2,3,4,5}`
`gof(2)=g(f(2)=g(3)=7`
`gof(3)=g(f(3)=g(4)=7`
`gof(4)=g(f(4)=g(5)=11`
`gof(5)=g(f(5)=g(5)=11`
