Key Concepts

Graphing a Function and Its Inverse

Graphing a function alongside its inverse helps visualize their relationship, as the graph of the inverse is the reflection of the original function's graph over the line y = x. This reflection rule aids in understanding the symmetry and behavior of inverse functions.

Algebraic Method for Finding Inverses

To find an inverse function algebraically, one typically replaces f(x) with y, swaps the roles of x and y in the equation, and then solves for y. This new expression for y becomes the formula for the inverse function f?¹(x).

Inverse Function

The inverse function reverses the mapping of the original function. That is, if a function f maps an input x to an output y, then the inverse function f?¹ maps y back to x. This relationship is often verified through the composition of functions, where f(f?¹(x)) = x.

Domain and Range Restrictions

For functions that are not naturally one-to-one, appropriate domain restrictions are necessary to ensure invertibility. Limiting the domain, such as restricting a quadratic function to non-negative values, guarantees that every output corresponds to one unique input.

One-to-one Function

A one-to-one function is a function in which each output is produced by exactly one input. This property is crucial for a function to have an inverse because the inverse function must assign a unique input for each output of the original function.
