Master Functions
Visually.
Understand every concept through interaction. See it. Move it. Discover the rules yourself — then prove them algebraically.
Rigorous. Beautiful. Interactive.
Every concept arrives visually first, then algebraically. You discover the rules — the math just confirms what you already saw.
Live graphs
Desmos embedded in every lesson. Drag, slide, transform — watch math respond.
Discovery-first
Sliders for every parameter. Build intuition before formulas.
Worked solutions
Step-by-step breakdowns on every practice question. Hints on demand.
Exam-ready
Timed exam mode with auto-grading and per-topic analytics.
Nine modules. One beautiful progression.
Function Basics
Relations, domain, range, and notation — the foundation.
Transformations
Stretch, reflect, translate — every shape from one parent.
Quadratic Functions
Three forms, one parabola — vertex, roots, and symmetry.
Exponential Functions
Growth, decay, and the power of constant ratios.
Rational Functions
Asymptotes, holes, and the forbidden denominators.
Absolute Value Functions
The V-shape — reflections and shifts in one clean fold.
Inverse Functions
Undoing — and the mirror across y = x.
Piecewise Functions
Different rules on different intervals — one graph, many pieces.
Function Operations
Add, subtract, multiply, divide — and compose.
Trigonometric Functions
Radian measure, the unit circle, and periodic graphs.
Sequences & Series
Arithmetic, geometric, and recursive patterns.
