If the mapping `f:{1,\ 3,\ 4}->{1,\ 2,\ 5}` and `g:{1,\ 2,\ 5}->{1,\ 3}` , given by `f={(1,\ 2),\ (3,\ 5),\ (4,\ 1)}` and `g={(2,\ 3),\ (5,\ 1),\ (1,\ 3)}` , write `fogdot`

Text Solution

Verified by Experts

We have,

f : `{1,3,4} rightarrow{1,2,5}` and `g:{1,2,5} rightarrow{1,3}`, are given by `f={(1,2),(3,5),(4,1)}` and `g={(2,3),(5,1),(1,3)}`

`Rightarrow {f} circ {g}` means `{g}({x})` function is in `{f}({x})` function.

`Rightarrow {f} circ {g}(2) ={f}[{g}({x})]`

`={f}(3)`

`=5`
