Even if you did not know that there was an inverse function x = g[y], why does your view in the infinitesimal microscope of y = f[x] convince you that there must be one, at least on a small interval? How does B
Given a function f(x), its inverse f^(-1)(x) is defined by f(f^(-1)(x))=f^(-1)(f(x))=x. (1) Therefore, f(x) and f^(-1)(x) are reflections about the line y=x. In the Wolfram Language, inverse functions are represented using InverseFunction[f]. As note

To find an inverse function in math, you must first have a function. It can be almost any set of operations for the independent variable x that yields a value for the dependent variable y. In general, to determine the inverse of a function of x, substitute y...
But when we consider the inverse function we run into a problem, because there are an infinite number of angles that have the same sine. For example 45° and 360+45° would have the same sine. For more on this see Inverse trigonometric functions. ...
