## What is Guess the Graph?

Graph Detective is an interactive educational app that helps students build intuition about mathematical functions by analyzing graphs instead of memorizing formulas.

Players are shown a graph without its equation and are challenged to reconstruct the underlying function by adjusting parameters or entering expressions. As users experiment, the graph updates in real time, encouraging exploration and hypothesis testing.

The app supports multiple difficulty levels:

Easy: Explore quadratic and linear functions using sliders

Medium: Enter full expressions including trigonometric, exponential, and logarithmic functions

Hard: Analyze composite and piecewise functions with minimal hints

Graph Detective features a custom math input interface optimized for learning, optional hardware keyboard support, and a built-in cheat sheet that explains common graph patterns and transformations.

## Key features

- Interactive graph analysis
- Function reconstruction challenges
- Real-time graph updates
- Multiple difficulty levels
- Custom math input interface
- Built-in cheat sheet
