If the function f:R→R be given by f(x)=x2+2 and g:R→R be given by – InterviewSolution

1.	If the function f:R→R be given by f(x)=x2+2 and g:R→R be given by g(x)=xx−1,x≠1, find fog and gof and hence fing fog(2) and gof(-3).
Answer» If the function $f : R \to R$ be given by $f (x) = x^{2} + 2$ and $g : R \to R$ be given by $g (x) = \frac{x}{x - 1}, x \neq 1$ , find fog and gof and hence fing fog(2) and gof(-3).
