In which of the cases of pair of function is the composition of function is commutative ?
f(x) = sin x g(x) = cos x
f(x) = sin x g(x) = x
f(x) = sin x g(x) =
f(x)= tan x g (x) = cot x
As we have learned
Properties of composite function -
The composition of function is not commutative.
- wherein
whenever , we have an identity function gof =fog
This is the special case for commutative property of composite function
Option 1)
f(x) = sin x g(x) = cos x
Option 2)
f(x) = sin x g(x) = x
Option 3)
f(x) = sin x g(x) =
Option 4)
f(x)= tan x g (x) = cot x
