Given the function f (xsquare-3) = lgxsquare / (xsquare-6), find the inverse function of F (x)

Given the function f (xsquare-3) = lgxsquare / (xsquare-6), find the inverse function of F (x)

Let t = x ^ 2-3, then x ^ 2 = T 3, so the function is y = f (T) = LG (T 3) / (T-3), to the power of ten, simplify t = 6 / (10 ^ Y-1) 3, then the inverse function is y = 6 / (10 ^ x-1) 3
