选项 A,y = x²不是一一映射,例如当 y = 4 时,x = 2 或 x = -2,所以没有反函数。选项 B,y = |x|也不是一一映射,当 y = 2 时,x = 2 或 x = -2,没有反函数。选项 C,y = 2x 是一一映射,有反函数。选项 D,y = sinx 不是一一映射,一个 y 值对应多个 x 值,没有反函数。

To solve the problem, we need to find the derivative of the inverse function g(x) at the point f(c), where g(x) is the inverse of the function f(x). 1. Understanding the Inverse Function: Since g(x) is the inverse of f(x), we have: g(f(x))=x and f(g(x))=x 2. Di...
