Module 8: Functions and Graphs – Leaving Cert Higher Level Maths This is one of those topics that feels abstract at first, but once it clicks, it opens the door to so many other parts of the course. Functions, graphs, and transformations form the backbone of the algebra-heavy content in Paper 1, and they're also deeply connected to exponential growth, logarithms, and calculus later on. If you're aiming for high marks, this is a topic you simply can't afford to half-learn. In this module, we’ll tackle: - Function notation, terminology, and composition - Inverses, injective/surjective/bijective functions - Sketching and interpreting graphs - Exponential and logarithmic functions - Transformations and related graphs - Past paper questions and tricky exam-style problems In our live, small-group grinds, I’ll guide you through the tough bits, answer your questions, and show you exactly how to present your work the way examiners want to see it. This topic trips up loads of students, but not you. Not once you’ve learned how to approach it properly.
