If f: R-{0} ightarrow R and g: R-{1} ightarrow R defined by f (x) = \frac{2x+1}{x^2} and g(x) = \frac{3x-1}{(x-1)^3} . Find the functional values to the algebraic operations \frac{f}{g} \binom {x} , (fg)(x), fog(x), and gof(x) by explaining the way of performing operations. Show all steps of calculations
