Let f (x) = (2x + 3) / (x-1) (x is not equal to 1), the image of function y = g (x) and the image of function y = F-1 (x + 1) be symmetric with respect to the straight line y = x, then G (3) is obtained

Let f (x) = (2x + 3) / (x-1) (x is not equal to 1), the image of function y = g (x) and the image of function y = F-1 (x + 1) be symmetric with respect to the straight line y = x, then G (3) is obtained

Because two symmetric functions on the line y = x are inverse to each other!
So g (x) is the inverse function of y = F-1 (x + 1)!
So g-1 (x) = F-1 (x + 1);
So g (x) = f (x) - 1
Generation g (3) = 7 / 2
