This high school math teaching material focuses on function reconstruction, guiding students from given graphical or textual properties to a complete function equation. Instead of analyzing a given function, students work in reverse and develop strong modelling and analytical skills.

Instructional Goal

Students learn to systematically translate conditions into equations, apply derivatives meaningfully, and solve systems of equations with confidence. The material supports conceptual understanding and aligns with U.S. high school math standards in algebra and pre-calculus.
