IB Mathematics AA HL – Log & Exp Functions (Module 5)

What you’ll learn
✓ Understand the structure of exponential and logarithmic functions, including domain, range, inverse relationships, and growth or decay.
✓ Solve exponential and logarithmic equations correctly, stating domain restrictions and rejecting invalid solutions as required in IB exams.
✓ Analyse and sketch exponential and logarithmic graphs, including transformations and the cases a>1 and 0 1 and 0 The second half of the course focuses on integration of exponential and logarithmic functions, including definite integrals and applications involving accumulated change. These ideas are then combined in modelling contexts, preparing you for multi-step IB exam questions.

The module concludes with worked IB-style exam examples and a full test with review, allowing you to practise writing solutions with correct notation, structure, and reasoning, exactly as required in IB assessments.
