Statement-1: If `f:R to R and g:R to R ` be two functions such that `f(x)=x^(2) and g(x)=x^(3)`, then fog (x)=gof (x).
Statement-2: The composition of functions is commulative.

A

`f(x)=x^(3),g(x)=x+1`

B

`f(x)=sqrt(x), g(x)=cos x`

C

`f(x)=x^(m), g(x), m ne n, m, n in I` (I is the st of all integers)

D

`f(x)=x-1, g(x)=x^(2)+1`
