a] (f + g) (x) = 1/x + (1 - x)/(1 + x)
                    = (1 + x + x - x²) / (x + x²)
                    = (1 + 2x - x²) / (x² + x)

b] (f. g) (x) = 1/x . (1 - x) / (1 + x)
                  = (1 - x) / (x + x²)
        
c] (fog) (x) = f((1 - x)/(1 + x))
                  = (1 + x) / (1 - x)

d] (gof) (x) = g(1/x)
                 = (1 - (1/x)) / (1 + (1/x))
                 = (x - 1)/x  /  (x + 1)/x
                 = (x - 1)/(x + 1)
