Question

In which line would the graph of the function f(x) be reflected to obtain the graph of f^-1(x). the inverse of f(x)?

Answer 1

Reflect the graph of y = f(x) in the line y = x to obtain the graph of y = f^-1(x). If (a, b ) is on the graph of y = f(x), then the corresponding point obtained by the reflection through the line y = x is (b, a). Basically, the inverse function switches x and y.
