## What is My Quadratic?

This app is an interactive graphing math book in which high school, college students and science lovers can observe and try out various ways of analyzing a quadratic function with graphing features.  

Students are gradually introduced the theory behind a quadratic function with various parameters. Mathematically, a quadratic function may be expressed in one of the three forms: the vertex form, the general form, and the factored form. This app shows techniques to find the zeros, the coordinates of the vertex, the y-intercept; to draw the corresponding parabola and its axis of symmetry; as well as to algebraically convert from one form to another. 

There are formula-specific calculators (CalPad) and parabola plotter (PlotPad) that help students characterize a quadratic function using domain, range, and variations; and visualizing the relative size and shape of the transformed parabola compared to the basic one.

• The vertex form: f(x) = a(x - h)² + k

• The general form: f(x) = ax² + bx + c

• The factored form: f(x) = a(x - x₁)(x - x₂)

## Key features

- Interactive graphing of quadratic functions
- Analysis of vertex, general, and factored forms
- Tools to find zeros and vertex coordinates
- Parabola plotting and axis of symmetry visualization
- Algebraic conversion between function forms
- Formula-specific calculators and plotter
