1.	Let `f : R to R : f (x) =(2x +1) " and " g : R to R : g (x) =(x^(2) -2)` Write down the formulae for (i) ` ( g o f) (ii) ( f o g) (iii) ( f o f) (iv) ( g o f)`
Answer» Correct Answer - `(i) (g o f) (x) = (4x^(2) +4x -1) " "(ii) ( f o g) (x ) = (2x^(2) -3)` `(iii) (f o f) (x) =(4x +3) " " (iv) ( g o g) (x ) = (x^(4) _4x^(2) + 2)`
