求满足方程f^-1x=f^2x^-1的所有x的和.
给出:f(x) = 16x+3 求:满足f^-1(x) = f(2x) ^-1) 的所有x的总和 解决方案:将f^-1(x) = f(2x) ^-1的两边应用到f^-1(x) = f(2x^-1),我们得到:f(f^-1(x)) = f((2x) ^-1)) 通过反向函数的定义,f^-1(x)) = x.另外,f^-2x^-1)) = f^-1 (x)  f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f) = f (x) = f (x) = f (x) = f) = f (x) = f (x) = f) = f (x) = f (x) = f) = f (x) = f (x) = f) = f (x) = f) = f (x) = f (x) = f) = f (x) = f) = f (x) = f) = f (x) = f) = f (x) = f) = f (x) = f) = f) = f (x) = f) = f (x) = f) = f (x) = f) = f) = f (x) = f) = f) = f (x) = f) = f (x) = f) = f)
