## Quick Answer

Solve for the inverse function f⁻¹(x) of a given math function f(x). Shows step-by-step algebraic variable swapping.

## Definition

An inverse function calculator is an algebraic solver designed to find the analytical inverse f⁻¹(x) of a one-to-one mathematical function f(x). It replaces f(x) with y, swaps the variables x and y, and solves the resulting equation to isolate the new dependent variable. It supports common function forms, including linear equations, rational functions, and power terms.

## How to Use

1. **Input your function** — Type the algebraic function f(x) you want to invert.
2. **Specify variable** — Enter the independent variable letter (usually x).
3. **View inverse steps** — Check the step-by-step algebraic isolation of y to get the final inverse equation.
