If f : A →B and g : B →C be two functions. Then, composition of f and g, gof : A →C is defined a ​

f: R  →R is defined by  f(x) = x²  - 2x + 1. Find f[f(x)] 

Let f: Q →Q be a function given by f(x) = x² ,then f ^-1 (9) =​

Let  g(x) = 1 + x –[x] and  

Then f{g(x)} for all x, is equal to:

If ƒ(x) = xsecx, then ƒ(0) =

Let f = {(1, 3), (2, 1), (3, 2)} and g = {(1, 2), (2, 3), (3, 1)}. What is gof(2)?

If ƒ(x) = tan^-1  x and g(x) = tan(x), then (gof)(x) =
