Let `f(x)=(x-1)/(x+1)` then `f(1)` is equal to

If f(x)=(x-1)/(x+1) then f(2x) is equal to

" If f(x)=(x)/(1+x) then f^(-1)(x) is equal to

If f(x)=(1)/(1-x), then f(f(f(x))) is equal to

Let f:(2,4)rarr(1,3) be a function defined by f(x)=x-[(x)/(2)], then f^(-1)(x) is equal to:

Let f(x)=x+(1)/(x), Then f(x^(3)) equals

Let f be a differentiable function such that f(1) = 2 and f'(x) = f (x) for all x in R . If h(x)=f(f(x)), then h'(1) is equal to
