Finding Functions – Edexcel IAL Pure 1 (Chapter 9.3) – Complete Lesson

A complete lesson on finding the equation of a curve from its gradient function and a point on it. A live family of curves shows how one point fixes the value of c, then a clear four-step method is used in six worked examples, including function notation such as f(1) = 3, roots and fractions, brackets, an unknown constant found from a gradient, and where a curve crosses the y-axis. The exam-style question combines integration with the tangent at a point.

Fully animated PowerPoint lesson, ready to teach from or to use for revision. Every worked example is revealed one line at a time, and diagrams and graphs are drawn live, so students see each step as you explain it. Includes learning objectives, a starter, common mistakes, practice with answers, an exam-style question with a full M1/A1 mark scheme, and an exit ticket. All questions are original.
