InterviewSolution

1.	Let `f : R to R : f (x) = x^(2) + 2 "and " g : R to R : g (x) = (x)/(x-1) , x ne 1 .` Find f o g and g o f and hence find (f o g) (2) and ( g o f) (-3)
Answer» Correct Answer - `(f o g) (x) = (x^(2))/((x-1)) + 2 (g o f) (x) =(x^(2)+2)/(x^(2)+1)` `(f o g ) (2) =6 , (g o f) (-3) =(11)/(10)`
