If the function f (x) = a + 3 / X-B and the function g (x) 1 + C / 2x + 1 are reciprocal functions, the values of a, B and C are obtained fast

Y = a + 3 / (X-B) is changed into the inverse function of x = B + 3 / (Y-A) function f (x) = a + 3 / X-B: y = B + 3 / (x-a) = B + 6 / (2x-2a) function g (x) = 1 + C / (2x + 1). By corresponding comparison, B = 1, C = 6, a = - 1 / 2
